SVT chiller connected, filled, run. Fill level is just above 3/4 (highest non-alarm level). There is a little bit of coolant left in the plastic jug, plus three unopened bottles.

Before attempting to take data, all of the FEB's were checked for sync.  The results are as follows: 

Summary: All APV's sync.

TKN - a longer exposition on the above:

  • FEB plate in - is cable clip in back really advisable?
  • must remember order: L46 hybrids, L46 data, L13 hybrids, L13 data
  • connected patch panel
  • connect flange to data last
  • lessons:
    • connection order: P4, P2, P3, HV2, HV2, P5, P1 ?
    • gentle with Dsubs!!
Found several ground faults:
  • Data cables were contacting flange and therefore shorting the following path:  Vacuum box -> mini-SAS shield -> mini-SAS ground -> FEB ground -> hybrid ground -> SVT detector ground (module, u-channel, box).  This is bad. 
  • Placed temporary mylar cone in flange.
  • Realized that bundling data cables will create flaky shorts among all FEB grounds.  Will need to passivate data cables over nearly their entire length in some way.
  • Found new short between SVT Box and Flange: ground lug on inside of flange meant for grounding the SVT was touching the flange.  Ground lugs have been covered in Kapton tape. Question: do we intend to use these?
  • Found short between FEB plate and SVT Box. Pins inside P4 were bent during connection and ground pin was bent into shell. This shorts the following path: FEB plate -> Patch panel -> connector shell -> FEB ground -> hybrid ground -> SVT detector ground (module, u-channel, Box).
  • Pins are redundant.  Pins were bent back into position as well as possible. Lower left pin has slight s-curve but pushed partway into pin block. Upper left pin has larger s-curve.  Both appeared to engage after repair but should be replaced.

Hacked coda to run from ppa-pc91245.

Run 837, L4t, bias to H2 and H3 (some issue with mpod crate), 
Run 838, L4t, bias to all four hybrids.

Run 840, full detector, ET ring adjusted for large events. Note that there was an error on dpm7 when I hit "Go" (something with FebCore). Things looked ok and DTM0 say Ack on all dpm's.

SVT chiller flow switch tested. Drained and refilled chiller in the process; level is just above 3/4, jug is empty. Chiller is running at stage 3 (we got a pressure trip at stage 4, which has not happened before - not sure why); this will be our normal setting. Estimated flow (based on pressure drop vs. flow switch trip) is 1.5 GPM. SVT chiller is connected to Wesley's EPICS stuff; work in progress.

2015-02-12

FEB chiller setup simplified so we just have the flow meter and flow switch (no manifold). This will make it easier to swap hoses or add components if we decide to do that before installation. Flow is unchanged at ~5 GPH (bottom of the flow meter range, below the flow switch range).

Noise performance results of first full test with all FEB's and hybrids powered on and biased.  Only a single COB was setup to run with CODA.  Overall, the noise on all FEB's that we took data with looked as expected.

Plan for next weekend:
  • Remove data flange and disconnect all cables.  Mark out desired lengths and passivation locations for all data cables. Clear all cables to inside of vacuum box for power flange removal.
  • Disconnect patch panel. Remove power flange.  Implement final grounding scheme on power flange.
  • Remove all data cables for passivation and/or replacement.  Fold and passivate data cables.
  • Install temporary lever support.  Disconnect linear shifts and flex pivots.  Remove linear shifts. Disconnect cooling and remove cooling feedthroughs.
  • Release vacuum box from top clamp. Remove cooling manifold. Remove vacuum box for packing.
  • Pull FEB cooling plate out as far as L1-3 allows. Remove P4 male DB44 from patch panel and cut all zip ties on those wires. Remove L4b LV mezzanine, if necessary. Replace lower-left pin and re-insert.  If pin doesn’t push in, then replace upper-left pin.  Otherwise; extract and mark all pins, replace upper left pin, reinsert all pins in new shell.  Reinstall P4 on patch panel.  Push cooling plate back into SVT box.  Use clamp to lock patch panel into SVT box. Use zip ties to lock lever lock into place?
  • Re-install L4-6 data cables. Re-install L1-3 data cables, if possible. 
  • Install hall probe in L6 electron-side window with DP190 and tape wire into place.
  • Secure loose data cables in SVT box. Tape foil to box from crane straps.
  • Lock lever lock into box for safety with clamp.
  • Lock L46 upper hanger with jam nut!
  • Prepare G10 pieces for SVT isolation.
  • Pack all needed items to take to Hall B for installation.
  • Prepare straps and tie-downs for lifts on Monday.
Plan for Monday:
  • Wipe down shipping plate from larger box and take into cleanroom on dollies. Lay foil along shipping plate for bottom of box. (15")
  • Release SVT from table.
  • Crane SVT onto shipping plate. (15")
  • Wrap and tape SVT box with foil. (15")
  • Roll SVT out of cleanroom. Cinch SVT down to shipping plate with tie downs. (15”)  *1’*
  • Install lid on inner box. (15")
  • Roll SVT out to crane area. (15")
  • Crane SVT into outer box.  Install foam. (15")
  • Close outer box. (15")
  • Crane outer box onto truck, levers facing rear, along with vacuum box and large crate with other items. (30”) *2’15”*
  • Slow truck move into Hall B down ramp. (30")
  • Crane inner box out. (15”) *3’*
  • Open inner box. (15")
  • Release SVT and crane up to pie tower. (15")
    • Pull SVT in and lower onto padded lift cart.
  • Move SVT to PS magnet (15")
    • Slow roll on lift cart to alcove.
    • Transfer to lift cart in alcove.
    • Lift up on cart, then shoulder-height lift to table in front of vacuum chamber.
  • Get SVT into position to transfer to vacuum chamber (15”) *4’*
  • Transfer SVT to vacuum chamber. (15”) *4’15*
  • Isolate SVT box with G10
  • Align SVT and lock into place (120")
Questions:
  • How heavy is the SVT?  Can we avoid the first crane lift with a manual lift?
  • Can we do to alignment on Day 1?
