MAIN Activities

[26-07-2006 15:51:14] RC: Ric updated lat-bt01 and lat-bt04 from LATTE-4.11.3-0.glast_online and INT-1.62.5-1.glast_online to LATTE-4.12.0-0.glast_online and INT-1.66.5-1.glast_online, respectively.
[26-07-2006 20:02:45] RC: Powered up CU system.
[26-07-2006 20:38:07] RC: Starting run control for test runs.
[26-07-2006 21:08:44] RC: Started run 700000610 - end2endBT.
[26-07-2006 22:19:11] CS: try a power cycle and a software reset of the VME to solve the GTCC phasing error problem.
Seems to work: the rate of the TEM error events is much lower that the run before
[26-07-2006 22:23:26] CS: Clarification: "reset of VME" in last comment means reboot with Ctrl-X in the terminal
[26-07-2006 22:55:28] RC: Started run 700000614 with the beam steered to a new location. We're also using a modified copy of end2endBT which doesn't allow LDF iterators to run of packet error events, which I'm guessing caused the seg faults.

MAIN Problems

[21:09] RC: Run 700000610 has packet error events, probably due to the high rate induced by the beam.
[21:10] RC: RunControl died with a segmentation fault on run 700000610
[22:00] RC: Took run 700000611 with the beam on. There were 221464 events counted, 218041 with TEM Errors, 2198 with Packet errors. Noticed that the discards rate was zero for multiple seconds and then spiked to some high value before returning to zero for some seconds. Presumibly it is due to the beam structure. Average event rate was 353 events/sec. The RunControl text window shows several warnings from LDF that 100s of bytes were found after TEM 2 contributions of 5 events. Apparently corrupted events are being iterated over, which is what caused the seg fault of the previous run. Why are we not detecting these events and not iterating over them? Need to investigate this.
[22:07] RC: Started run 700000612 with beam. See both TEM error events and packet error events.
Event rate seems to be about 50 Hz for a while and then bounces up to KHz for short bursts.
Carmelo found that all TEM error events appear to be TEM 3 GTCC phasing errors.
Run stopped with 98410 events, 988408 TEM errors, 1027 packet errors.
[22:56] RC: RUn 700000613 seg faulted.

MAIN Activities

[26-07-2006 23:25:32] RC: Enough for today. Powering down.

MAIN Problems

[23:08] RC: Even though the end2endBT code that is being run for run 700000614 does not iterate over packet error events, we're still seeing some events with 300 or so bytes after the end of the TEM 2 contribution. This means that there are corrupted events that have the TEM error bit set but are not navigable.

Also, all events in this run have TKR cable phasing errors. Perhaps this is an after effect of the previous run's seg fault?

MAIN Problems

[17:23] CS: run in self trigger (BT-3) that crashed: 700000669.

Shiftid: 200607272

General Note:

Calorimeter calibration : hit the center of all logs.
Choose BT14 trigger conditions.
Looking at GOSED (evt display), we've seen that the majority of the events have almost nothing in the tkr and cal : BT14 is cal low and internal trigger.

Testing the BT configurations
Johan creates BT16 : four range readout/zero supressed/external trigger
run 700000700 taken with this new readout
looking at GOSED (evt display) : the events have diagnostic data

For all runs we need to check timing since for some of them TEM diagnostics is on and we have not seen plots validating the timing settings yet

MAIN Activities

[28-07-2006 06:35:16] CS: WARNING for offline people: XYTable position in the rcReport.out for run from 700000701 to 700000736 are wrong and are all the same, but the .txt file in the export dir has the correct settings.
This appened because the operator should go in the RunContro RESET state before press the Start button or the GUI that collect the ancillary information is not updated.
[28-07-2006 07:35:02] CS: run 700000745 Aborted with ~3kEvts due to NO BEAM. Let's wait for the restarting of the beam and repeat a run with this settings

MAIN Activities

[28-07-2006 17:18:05] CS: Sycnh test: we added a delay in the "reset veto" signal, this increase a dead time but make the system stable at list with an ext trigger rate up to 5kHz. The event rate is ~200 evts per spill, dead-time dominated.

General Note:

Study trigger alignment for baseline runs BT1.
Calibrate ACD.

MAIN Activities

[29-07-2006 01:33:42] LB: Realised that the TTL external trigger had the wrong polarity and the signal was off by 1 us.
Fixed, now beginning trigger alignment.
[29-07-2006 01:38:33] LB: Alignment between TKR and CAL_LO studied and understood. Documented on confluence.
[29-07-2006 01:42:34] LB: Realized that, due to a wrong xml, the config_o register of each GCFEs were overwritten in such a way that the CAL_HI trigger primitive was masked.
Fixed.
[29-07-2006 01:45:07] LB: Run 700000822 is taken with ext_delay set to 0x4 to see all the three primitives.
Putting ext_delay back to 0x8
[29-07-2006 01:49:01] LB: Runs 813, 815-816 and 819-820 have the wrong particle id (should be electrons instead of pions).
[29-07-2006 02:09:52] LB: Switching to the trigger alignment for the ACD, which is the last remaining to be done.
The settings we've been running with up to this point are:
<hitmap_width>15</hitmap_width>
<hitmap_delay>6</hitmap_delay>
<hitmap_deadtime>0</hitmap_deadtime>
<hold_delay>34</hold_delay>
<veto_width>5</veto_width>
<veto_delay>0</veto_delay>
[29-07-2006 02:12:27] LB: Last message got screwed up by the e-log
[29-07-2006 02:19:18] LB: Run 700000825 crashed with a segfault.
[29-07-2006 02:30:48] LB: Check all the ACD delay values and it seems like they agree with the table that Eduardo put in confluence, though the informations are not completely consistent.
Also the ROI signal seems lined up with the other primitives within the trigger window.
[29-07-2006 02:38:24] LB: Changing the veto_delay from 0x0 to 0x16 actually shifts the roi primitive into the trigger window by ~5 ticks.
[29-07-2006 02:41:05] LB: All ACD registers put back to the original values.
[29-07-2006 02:45:59] LB: ACD high voltage changed from 760 to 810.
[29-07-2006 02:56:44] LB: Make a new test configuration BT12. Identical to BT1 except that the redout is unsuppressed.
[29-07-2006 02:58:28] LB: Doing a power cycle and a VME reset to see if the situation with the errors gets better.
[29-07-2006 03:15:07] LB: Run 700000829 is taken with the table far away from whatever tile. It's a BT12.
Good for ACD pedestal determination.
[29-07-2006 03:24:31] LB: Run 830: BT12 with beam on tile 4 (PMT 7). Landau peak roughly 800 over the pedestals.
[29-07-2006 03:28:41] LB: Run 831: BT12 with beam on tile 3 (PMTs 15 and 17). Landau peak roughly 600 and 1000, respectively, over the pedestals.
[29-07-2006 03:31:34] LB: Run 832: BT12 with beam on tile 2 (PMT 9). Landau peak roughly 1000 over the pedestals.
[29-07-2006 03:34:19] LB: Run 833: BT12 with beam on tile 1 (PMT 11). Landau peak roughly 3000 over the pedestals.
[29-07-2006 03:36:31] LB: Run 834: BT12 with beam on tile 0 (PMT 13). Landau peak roughly 2000 over the pedestals.
[29-07-2006 03:43:57] LB: Going down again with the ACD high voltage tp 760 V.
[29-07-2006 03:44:51] LB: Doing another power cycle and VME reset.
[29-07-2006 04:06:02] LB: Repeting the procedure for the ACD with the new voltage...
Run 837 -> tile 0 -> peak @ 1600
Run 838 -> tile 1 -> peak @ 2000
Run 839 -> tile 2 -> peak @ 1000
Run 840 -> tile 3 -> peak @ 500 and 800 (two PMTs)
Run 841 -> again for tile 3 with a bit more statistics, since the shape is a bit strange.
Run 842 -> tile 4 -> peak @ 500
[29-07-2006 04:14:45] LB: Run 843 is and AcdPedestal.py run.
Pedestal file correctly copied into the repos.
From now on ready for zero-suppressed data taking runs.
[29-07-2006 04:22:29] LB: Run 844: zero suppressed data with the beam hitting tile 4.
[30-07-2006 00:47:41] JB: Testing synchronization with Ancillary : 700000845

MAIN Problems

[01:56] LB: Run 700000823 (5 GeV pions on axis) has plenty of packet error events.
[02:37] LB: Got this message that I've never seen before on run 700000826.

WARNING:root:Socket purge encountered 816580 bytes of stale data

MAIN Activities

[30-07-2006 10:53:00] LB: Run 856 was for testing a new schema file. The trigger was actually external on a scintillator with a fairly low threshold (essentially noise).

General Note:

Testing synchronization triggering on noise

MAIN Activities

[30-07-2006 16:24:37] CS: note on problem reported: sorry, I added a 'problem' instead of an 'activity'
[30-07-2006 16:45:07] CS: run 700000866: synch test with ~10KHz of trigger rate, ~300Hz of aquired event rate. All OK

MAIN Problems

[16:23] CS: synch test: BT12, CU unsuppressed
[16:29] CS: I had a problem with run control during sych test: after stopping the run and starting again we had e trigger sweep time out error. so we always close and reopen run control after a run.
[20:33] RC: Noticed that the HSK alarm system is complaining about HTEM[3].tkr_c6_t0. Sandro is looking into it.

Shiftid: 200607302

General Note:

Waiting for the beam to return.

Benoit introduced a gate in the external trigger path that prevents retriggering the CU faster than T mSecs, where T is adjustable. This is for the case when the Ancillary System isn't participating and providing that gate through its own deadtime The proper setting of T is still to be found but is expected to be around > 1.3 mS to prevent being rate limited by end2endBT's analysis code

Shiftid: 200607310

General Note:

Waiting for the beam to return.

MAIN Activities

[30-07-2006 23:10:00] RC: Changed the computer clocks to local time (GMT + 1) at the request of many.
[30-07-2006 23:33:59] RC: On Eric Siskind's recommendation, changed the configuration files to set the GTCC Configuration register so that the FIFO full condition (data) is 0x3e = 62 instead of 0x20 = 32 in all cases (see the TEM manual for details). The claim is that this will reduce the rate of TKR FIFO Full errors reported by the TEMs at the expense of extra dead time. We should take a CU-only run with beam to verify the effect.

Also on Eric's recommendation, I removed the non-existant FREEs from the AEM configuration FREE board masking field so that they don't need to be timed out when building the event contribution.

I also removed the nonexistant TKR of Tower 1 from participating in the trigger (GEM Input Enable Towers_0_3 register).

MAIN Problems

[23:07] RC: Sandro did something to make the CU cool down. Temperatures are falling but alarms haven't ceased yet.

[03-08-2006 16:28:52] RC: Installed APC UPS software on lat-btserver. Its RPM and other files are in /gnfs/redhat/RHEL4/MCR.
Ran the APC config.sh configuration script. It requires an account, for which I gave 'online' with the usual password.
Attached the UPS' to the serial ports since I couldn't get the USB method to work. They are all set up as 'smart'.
Did this for lat-btserver, lat-bt01 and lat-bt04. One of the lat-btserver monitors (insufficient cables to do the other) and the switch were also put on the UPS.
[03-08-2006 16:34:41] RC: Updated INT release on lat-bt01 and lat-bt04 from 1.66.5 to 1.66.9. This includes the fix to build a mask that does not include the tower 1 tracker in the trigger (GEMIE.towers_0_3 register set to 0xfd8 instead of 0xff8).

[05-08-2006 18:24:32] RC: Runs 991 through 1053 are debugging runs for the CAL CPT problem. It turns out that the problem was due to the CU some how being in a funky state. Turning off the front ends, issueing LCBC_lat_reset, rebooting the SBC and turning the front ends back on cured the problem. Some of these runs should show the funky state of the CU. Working around the exceptions in the code due to the messed up date showed that there were lots of messages like 'Found 32 bytes after the TEM 3 contribution', always 32 bytes.

[07-08-2006 17:46:09] RC: The time on lat-bt01 and lat-bt04 were wrong (set to the time value in California, but with CEST timezone). It's not clear that lat-btserver is serving ntp as it should, or that lat-bt01 and 04 are listening to lat-btserver for their time signal. I fiddled around a bit after setting the time value to the correctish local time value (so that at least runs aren't too mislabeled) and will check to see whether the times between machine synchronize. The ntp config files look to be correct, but they didn't look horribly wrong when I started.

MAIN Activities

[08-08-2006 06:12:50] CS: run 1138: BT3 - the beam is coming so we are collecting all kind of particle. Particle type should be 'All Particle' instead of 'Cosmics'.
[08-08-2006 06:16:09] CS: run 1139: BT2, the beam is still not perfect, we try to collect some data in self trigger....
[08-08-2006 06:41:48] CS: run 1140: BT2, same conditions of previous run.
Beam is here! Instant Rate increased!
[08-08-2006 06:51:06] CS: run 1141: BT2 - studing the beam in self trigger.
Avverage rate ~ 400Hz, peak instant rate up to 3kHz
Pile-up seems to be dominating in Bruel plot: fraction of event with more than 50 log hit is up to 40%
There are both Tem error and packet error, but we now that this can appen in this trigger condition.
Stop the run after 220 kEvts.
[08-08-2006 07:01:15] CS: run 1142: BT1 - people are playing with external trigger, so it can change during the run. We want to check trigger timing.
Instant rate up up ~1.5kHz
[08-08-2006 07:11:41] CS: added BT4 in config file: like bt1 but treq for tkr amcl cal delayed in the center of trigger window
[08-08-2006 07:15:30] CS: run 1143: BT4 - same condition than previous run. we want to see trigger primitives delay...

QF03: positive current set, position = 52 for both H and V slits
S0 rate ~ 8kHz
Hardware trigger rate 60 Hz
Almost 0.6% of event with more that 53 logs in the CAL, but we see some clear pile-up events in gosed
Spill signal removed from trigger logic in the middle of the run (after ~900 seconds fron the start of the run), no great effect in the trigger rate.
XYTable position changed during the run.
[08-08-2006 08:00:51] LB: Run 1145: new reference run @ 5 GeV. Slits position changed to 53.
S0 ~ 10000 particles per spill.
The 10 s spill gate is disabled as spills are evenly distributed in the cycle.
The fraction of events with more than 53 logs hit in the CAL is 0.12 %.
[08-08-2006 08:06:49] CS: beam disappeared after less than 1000 second of run 1145
[08-08-2006 08:53:20] CS: run 1146: same condition of previous run with pile-up inspector circuit ON.
The beam is really unstable and no information from control room (it seems that they don't really understand what's going on)
S0: ~7000 counts per spill
Hardware trg rate ~ 50 Hz.
Beam disappeared after ~1400 seconds
[08-08-2006 09:31:45] CS: run 1147: beam seems to be back. We repeat a run with the previous settings with a good beam:

[08-08-2006 11:27:17] CS: run 1154: after second intervention on the setup: S3 moved 45 mm in the -X direction (CU coordinate system)
people need to enter the area....
run stopped with Ctrl-C after 4900 evts.
[08-08-2006 11:49:28] CS: setup modification: S3 edge is 50 mm with restect to red line (-X)
trigger is changed (S0&S3)
[08-08-2006 11:57:04] CS: run 1155: tagger align. new position of S3. now selecting all particles.
new intervention needed.

[11-08-2006 09:40:22] CS: run 1204: sych run with electron at 0.5 GeV (after correcting magnet setting).
There is still a problem with magnet settingd: QFO03 and QFO01 can't be set at nominal values (6.3 A and 7.8 A), they have been set at 8A
S0:13K count per spill
HW trg: 900 count per spill
s0*c1*c2: 10k count per spill
The beam is not good: lots of 0 in front chambers and the beam profile seems to be larger than the one at 3 GeV.
Nicola is looking at PMT timing to check that delay among all triggers signal is correct.
[11-08-2006 09:47:23] CS: note on run 1204: we got two spills in the middle of the run. Beam divergence: 9 mrad on YZ and 12 mrad on XZ.

DAQ trg: 300 count per spill
beam divergence: 6.3mrad on XZ, 5mrad on YZ
[11-08-2006 10:10:15] CS: it seem like:
- Sh a bit inefficient.
- S2 is triggering also on the light guide.
- S0 dominate the trigger and gets everything inside the beam (compared with previous runs) .

We try to turn on the bending magnet to see if we can take gamma with 1 GeV beam,
the magnet current set to 240 A (used to be 600 for 2.5 GeV runs)

DAQ trg: 100 count per spill

Lot of 0 cluster in chamber 2 and 3, we need to tune the bending magnet and/or improve the veto to select a small spot.

Stopping the run with Ctrl-C, need to better understand this feature.
[11-08-2006 10:46:19] CS: run 1207: run with same setting of previous one but with S1 in the trigger.
this run is to see if the zero that we see is a trigger or magner problem:
- it seem that it's a trigger issue: now the fraction of zero seems similar to what we saw in the other physics runs.

S0: 14 k count
HW & DAQ trg :20 counts

Run stopped (Ctrl-C).

Checking trigger timing to evaluate Sh efficiency and decide if hardware intervention is needed.
[11-08-2006 11:05:00] CS: Hardware intervention in the area.
S3 is now in veto very close to S2 light guide. This is to select a smaller spot of the beam and reach a good tagger efficiency with 1 GeV beam. Look at the paper logbook for a picture of scintillator geometry.
[11-08-2006 11:34:13] CS: run 1208: new trigger with S3 in veto, gamma run with 1 GeV beam and 240 A magnet.

The beam spot on the tagger chamber is ok. the nunber of 'zero cluster evts' is also resonable.
The intervention on the trigger logic actually fixed the problem.
This is a good run for analysis. Bravo Mazziotta!
[11-08-2006 12:08:34] CS: new pedestal run for AD: 4318
Slits position changed from 51.5 to 52: S0 rate passed form 14 kCount to 20 kCount per spill
[11-08-2006 13:19:25] JB: run 1209: good tagged run with 1GeV beam.
trigger counts per spill (2 spill per cycle):
S0: 20k
HW: 80
DAQ: 70

after 3.5k event slits closed to 51.5: we don't see significant change in DAQ rate so we will continue running in this condition.

after 12k evts: third spill has been added (actually we have a third spill every two cycle).
S0: 29k
HW: 200
DAQ: 200

after 25k : beam intensity is lower and we get back to 2 spills only

around 30k : SYNCHRONIZATION LOST !
stopping the run, first 30000 events should well sycnhronized...
for the event for which the synchronization was lost the DeltaEventTime was 128s that is corresponding to the turnover of the 2nd GASU counter.
[11-08-2006 16:34:04] JB: 700001210 : Synchronized Tagged gamma with 1GeV electron beam, going for 70k to get all the statistic
+ beam intensity is very low : DAQ rate ~ 15events/spill and S0 ~ 2700events/spill
+ after 12k : we have 3 spills taking ~200 events per super cycle

General Note:

Setting Beam energy to 1GeV and Magnet current to 240A
Changing Beam momentum, Piergiorgio noticed that the Focus was set to the standard value instead of 10m that corresponds more to the CU position. We set the Focus to 10m...it may explain the law rate observed yesterday ?
Checking Cerenkov pressure at the beginning of the Tagged photon runs: C1=0.8 C2=0.9 OK
Starting Tagged Photons Synchronized : E=1GeV, Pos=4, I=240A
Beam is stable through out the shift
Synchronization Problems : very likely because of the scaler cable for the AD TimeStamp, after fiddling a bit everything is back to normal
Starting Tagged Photons Synchronized : E=0.5GeV, Pos=4, I=120A
too slow for a day shift so we do :
Starting Tagged Photons Synchronized : E=1.5GeV, Pos=1, I=360A

MAIN Activities

[16-08-2006 07:09:06] JB: 700001406 : 6GeV/c protons, 90degrees, entering Tower 3
Erik runs the AD DAQ to monitor the beam and notes that it's not well centered in X

[16-08-2006 07:12:10] JB: 6GeV/c proton beam is now centered with value 141.5A on BHZ03
[16-08-2006 07:46:15] JB: 700001407 : 6GeV/c protons, 90degrees, entering Tower 3. BHZ03 moved from -143.35 to -141.5A to better center the beam on the cerenkov as detected by the ancillary system with the si chambers in the beam
[16-08-2006 08:28:43] JB: Run 700001408: 6gev p at 90 degrees through log 2 - 100K evts. CU configuration is BT22 (4-range readout, non ZS). Purpose is determine cause of apparent pedestal drift with high rate p runs; this run aims at reducing readout with still high rate of particles going through (counts on S0 is 60Kpart/cycle)
[16-08-2006 08:30:42] LL: Reduced slits from 51.5 to 50.5. Counts on S0 reduced from 60K/cycle to 12K/cycle, hdw trigger counts reduced to 1.5K from 3.2K. Will take 2 runs, BT1 and BT22 to check particle rate effect on pedestal drift with reduced beam rate
[16-08-2006 08:36:04] LL: Run 700001409: 6 gev p, 90 degrees, log2, BT1, hdw trigger reduced factor 2 wrt to previous runs (now 1.5k part/cycle)

MAIN Problems

[06:26] JB: I have just noticed that the HouseKeeping Server is not running.
Starting it around 8:15AM
Looking at the GUI and zooming out, we can see a big hole with no data for the whole night.
BTW Ric, when I zoom out to see 12hours of data on the GUI the canvas explodes.

[16-08-2006 16:05:37] CS: some of the runs have a wrong position recorded in the db. Here is a mail from Benoit:

------------------------------------------------------
Hi,

the table position mentioned in the data base for the proton runs
1365-1391 is wrong. It should be (theta, x, y, z)=(30, 93, 23, 600)
instead of (-51,....)
corresponding to the previous setting used for positrons. Because of a
communication problem occuring from time to time between PCs, the file
containing these data was not updated.
Eduardo, could you please try to have this corrected whenever you find
the time? Thanks.

problem in the beam spot. it doesn't seem to be in the right position....
[16-08-2006 19:58:11] CS: previous run stopped with ctrl-C, synch lost for last events..
we don't see the beam in the first chamber but it is there in the second one.

- old pedestal for AD.
- some hardware issue with chamber 0

try redoing the podestals...

ABORTED: the HW trigger is still too low. Seems that the cherenckov counts a very low rate (few evts per spill).
Lowering the threshold didn't help. investigation in progress.

MAIN Problems

[13:47] JB: POWER SHUTDOWN at 11:30AM this morning
The emergency button was pressed by mistake in the "offline barrack".
All the UPS did their job but as we could not find the way to turn the power back on, we prefered to turn off everything while the expert was coming.
+ Powered Off cleanly : CU, VME crate, bt-server (besides it's own crash pb at power off), lat-bt01, lat-bt04
+ Powered Off by cut off : pcglast23, pcglast22, pcglast31, pcglast30, pcglast37, all Nim and VME crates, +5V and +55V PS of the tagger
+ Powered Off when the UPS in the cave died : PC windows, Agilent 28V PS, +9V PS of the datalog
->I could not save datalog live time data because I could not connect to the Windows PC

POWER ON around 12:30PM
Everything went back smoothly but :
+ the 2nd screen of the lat-btserver, I had to install again the nvidia drivers following the howto and it worked again
+ I am not sure about the way I restarted the datalog software on the windows PC...

Beam off at 1:05 am. Beam back at 3.00 am. Shift crew still alert and awake.
Beam back for 1 minute, than off again for 30 minutes. Called control room, they say they have exchanged a power-supply for one magnet and when they switched it back on, the spare also failed. Ended the shift, since control room says it will take long.

tkr, cal_le, cal_he seem now aligned. They arrive 3 ticks after the external trg.

The beam was on tower 3, need a run on tower 2 to check that there are no changes
[06-09-2006 05:26:37] CS: run 1765: same as before but on tower 2. Only cal_he sems to be 1 tick slower, but the setting can remain the same

There was a problem with one of the values of the magnet. Somehow, the value changed,
and the new value was not appropriate for our needs. Very few electrons were triggering
the system.

Benoit changed this value (put back the default).
Benoit also changed values for the collimators; which were not wrong, but not really
appropriate.

The rate is now 1000 triggers per spill.

This configuration will be repeated in the next run.

[16-11-2006 14:25:15] CS: 700002458 : First cosmic rays run for integrity check of the whole DAQ and hardware after setup.
Lots of packet error events and then the acquisition stopped with the message:
"CRITICAL:root:Trigger sweep timed out before all events were drained".

After pressing the stop button we had lots of error during the snapshot.
GSI people worked on the cabling...but we doubt that this can be the cause.

Openin the register browser: we have 'timeout errors' only sometimes and ramndomly distributed in several registers.The comunication is unstable.
Nothing stange on debug terminal or HSK.
[16-11-2006 14:30:37] CS: johan found that the CU data cable was not perfectly plugged. This was probably due to the handling of the cable by GSI people.

In fact the 4 LAN cables were on the ground, from the rack barack to the control barack. Now the cables pass under the floor, using the standard cable path.

[18-11-2006 22:47:53] CS: Changing the schema to the new one with special Tracker layer splitting
to study FIFO full issue with the beam
the schema is "CU_BT_GSI_LayerSplit.xml"
[18-11-2006 23:05:39] CS: The new schema file is meant to read half of the planes completely form the LO side and half from the HI side.
The following table describes the Layer-Cable Controller correspondence in the "CU_BT_GSI_LayerSplit.xml" schema

GTCC ID='1' reads Layer ID='0, 2, 4, 6, 8'
GTCC ID='0' reads Layer ID='1, 3, 5, 7'

GTCC ID='2' reads Layer ID='0, 2, 4, 6, 8'
GTCC ID='3' reads Layer ID='1, 3, 5, 7'

GTCC ID='4' reads Layer ID='0, 2, 4, 6, 8'
GTCC ID='5' reads Layer ID='1, 3, 5, 7'

GTCC ID='7' reads Layer ID='0, 2, 4, 6, 8'
GTCC ID='6' reads Layer ID='1, 3, 5, 7'
[18-11-2006 23:18:15] CS: 700002576: BT-50: 100kevts with special layer splitting
- basically half of the layers are read with the LO GTRC and half with the HI GTRC
- rate 1800 count/spill, ~ 300 Hz
- ~0.3% FIFO full events, used to be 4% in standard config
