Pulse Selector in the Hutches

Tuesday Jul 2nd

Initial XRay aligned positions:
Y position: 0.0000 mm
X position: 0.1512 mm

Test examples
Single shot 10 images

   ccdtake(1,10, bShutter=True)
   

Burst mode 3 shots 100 images

   ccdtake(3,100, bShutter=True)
   

Alignment Laser used to test the system

1. To insert the laser

   Code Block
   In [2]: rl2.movein()

2. To remove the laser

   Code Block
   In [2]: rl2.moveiout()

Results: Tests doesn't work satisfactory. Problems found in Mcode:

1. Integrate 4 shots instead of 3 (using ccdtake(3, 1 , bShutter=True))  OK
2. missing some shots when in 2 shots mode. SOLVED (USING MODE 3.2)
3. Stopping the program (:RESET_PG 1) tooks long time than before 1-3 sec more)
   Needed one variable to check if RESET_PG is completed or if is OK to change mode.
4. Switch from mode 1 to 3 still doesn't work. Example:
   ccdtake(1, 1 , bShutter=True) WORKS
5. ccdtake(3, 1 , bShutter=True) FAILS!
   Still needs to do HOMING
6. Fast OPEN and CLOSE doesn't work.

Monday Jul 1st

New tests with new ioc version (new MCode version)
Features:

• New MODE (MODE 3.3)
  • One EVR Trigger OPEN, Next EVR Trigger CLOSE OK IT WORKS
• Fast OPEN and CLOSE commands NEED TO BE TESTED

TO BE IMPLEMENTED IN THE MCODE ASAP:

• Start position insensitive
• HOME (Index Mark) position set to zero (DIAL)
• START position (insensitive) relative to HOME (USER)
• Record to report position (Encoder) as monitor at any time

TODO and issues in XCS

==================================================

in xcs-control:

caput XCS:SB2:MMS:09:SET_VE 0

modify reg/d/iocCommon/sioc/ioc-xcs-trigger-ims/startup.cmd

to point to working area,

ssh ioc-xcs-mot1

kill ioc (telnet localhost...)

boot ioc from reg/d/iocCommon/sioc/ioc-xcs-trigger-ims/startup.cmd

===================================================
to fast open/close:
caput XCS:SB2:MMS:09:MODE_OPEN 1 (C2 should be around 655)
caget XCS:SB2:MMS:09:SE_L (to be read 4)
caput XCS:SB2:MMS:09:MODE_CLOSE 1 (C2 should be around 0 or 2x655)
caget XCS:SB2:MMS:09:SE_L (to be read 5)
===================================================

   1. START STOP mode3.3

         SET_TG 2

         SET_MODE 3

  2. FAST OPEN/CLOSE PV

  3. START POSITION INDEPENDENT:

1. ISSUE: No counting -> trigger "burst stop" sometimes
2. FIXME: Avoid arm/disarm
3. TODO: Benchmark time needed for position correction
4. FIXME: Start position dependent on present position
5. TODO: If
   position correction takes <= 10ms the do each time
6. TODO: Home offset as PV
7. TODO: Make Aperture Angle as VAR and PV (to be changed as needed)
8. TODO: Dial zero @ Encoder Home marker
   User zero @ "Aligned" position (means that RESET_PG reset only users) - to be discussed with Jeff
9. TODO: Fast Open/Close PV

1. NEXT: Uses First Trigger to Open, Second Trigger to Close
   The PP listen then for just one Event Code.
   Example of sequence:
   84 1 -> PP
   85 2 -> DAQ
   85 1 -> DAQ
   85 1 -> DAQ
   84 1 -> PP
   85 1 -> DAQ

Setup Lab tests

XIP Pulse Selector: Files, modes, schematics

Setup Lab: EVR Settings

Setup Lab: Working with the EVR from pslogin

1. in pslogin type (you need to have your securekeys):

   Code Block
   ssh ioc-tst-cam5 /reg/neh/home1/paiser/bin/evr.sh EVR=TST:CAM:05:EVR

2. Then configure EVR as you need manually...

Setup Lab: In case the server ioc-tst-cam5 was power cycled

1. Connect to the server:

   Code Block
   ssh ioc-tst-cam5

2. Run the startup command that contains EVR ioc in:

   Code Block
   sudo /reg/d/iocCommon/sioc/ioc-tst-cam5/startup.cmd

3. You should see with psproc:

   Code Block
   [paiser@ioc-xrt-xcscam04 ~ 12:18:20] psproc PID USER-ID SIOC COMMAND HOSTNAME PORT 4851 tstioc caRepeater procServ ioc-xrt-xcscam04 30000 5147 tstioc ioc-tst-cam5 procServ ioc-xrt-xcscam04 30001 5150 tstioc ioc-tst-cam5 procServ ioc-xrt-xcscam04 40000

Setup Lab : In case you need to power cycle ioc-tst-cam5

Code Block
ipmitool -I lanplus -U ADMIN -P <you_should_know> -H ioc-tst-cam5-ipmi power status ipmitool -I lanplus -U ADMIN -P <you_should_know> -H ioc-tst-cam5-ipmi power reset

Where: <you_should_know> is the standard ipmi password that you_should_know...

Mode Descriptions

Mode 1: Single pulse
Mode 2: Continuous trigger

Mode 1 and 2 should be the same program, as the Seq will generate the pulses to the motor, and open/close operation shouldn't make any difference whether it is 1 or more. The motor sees a trigger and moves.

This mode is accessed by <PV>:RUN_MODE2

Mode 3: The motor opens on a pulse, counts N pulses and closes on the Nth pulse. The pre-trigger and close trigger should be factored in by the upper layer software to determine the proper N value to put into the motor. All the motor does is, open on N=1, count, then close on N=N.

This mode is accessed by <PV>:RUN_MODE3

Mode 1 was programmed like just mode 2 with a User "Trigger" enable/disable, which may or may not be useful for us. Sort of like 2 layers of enabling, versus just 1 for mode2
This mode is accessed by <PV>:RUN_MODE1

Reset Modes to start new mode:
<PV>:RESET

Homing Sequence

1) EPICS Motor Record: HOMF

Motor Interlock Scheme

Screenshots

Pulse Selector Test/Checkout Procedure (6/10/2013)

X motor calibration

• Found offset from X zero position: 5.8075 mm from + limit
• Offset for X zero position: 5.7332 mm from - limit
• Limits performed as expected, and in place before hardstops

Y motor calibration

• Offset from +Y limit to zero: 15.6689 mm
• Offset from -Y limit to zero: 7.9956 mm
• Limits performed as expected, and in place before hardstops

New Interlock:

Add Y motor interlock, position >= 2 mm above 0 position, no X movement allowed

X-Y interlock stopped working today, need to investigate.
