ITW is argon venting now.

Argon venting of ITW is done. It took about 4.0 to 4.5 hours to vent the ITW with 2-3 psi argon. The CG4 and CG4S showed 35 to 36 torr on epic page when mechanical gauge is 760torr in electrical. Argon gas bottle is closed in electrical room.

Entry  Thursday, January 30, 2020, 12:06, David Wang, ITW, Standard Operation, TM4, , ITW primary and secondary vacuum seals leak check.  

Connected LD to ITW(TM4) TP1. Base LR 0.0Xe-9 atm.cc/sec. Base pressure 0.0Xe-4 torr. All ITW primary and secondary air to vacuum seals are helium spray checked. There is a 5XE-9 atm.cc/sec leak on  exit2 module top cover plate o-ring seal. The location is on west  side, south corner of the plate. Hi- vacuum resin are sprayed to leak area, and leak checked  again. The leak is gone.   The other seals on ITW vacuum vessel are good.

With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi.  I adjusted ITW dump pressure to 25 psi by changing the return line side pressure relieve valve.

ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi.

2019-01-30: Water only supply to 2A beam lines only on both side, No TM2 and TM4 in water loop.  ITE dump pressure 27psi, ITW dump pressure 27psi.

Entry  Friday, January 03, 2020, 13:15, Adam Newsome, Crane, Repair, , , Target Hall Crane PLC Module/Battery Replacement 
The Target Hall Crane bridge and trolley motion was lost after a period of the crane having power disconnected over winter holidays. This is reported in the following e-log: https://elog.triumf.ca/TIS/RH-ISAC/2039. This issue is a duplicate of what happened in 2019 at this time: https://elog.triumf.ca/TIS/RH-ISAC/1845

It was determined from troubleshooting via PLC indicator lights that the memory battery had died during the power-off time, and because of this, the program stored was lost. Note that this is an anomaly - the battery should have lasted much longer than the shutoff duration of ~2 weeks.

The SLC500 module was replaced with a spare, which contained a new battery. The old SLC500 module is still functioning but the battery has been removed (spares will be ordered) - this module is stored in a cabinet drawer in the control room. It will need to be re-programmed if re-installed as the program was lost. The original program titled TargetHallCrane.RSS was downloaded to the module. The crane was tested in local mode and determined to be functioning.

Entry  Thursday, January 02, 2020, 10:10, David Wang, Crane, Standard Operation, , , TH crane issue. 

Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control  on N-S, E-W and up-down movements do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded the program. I guess  the battery is drained out very fast for some reason. So, We face the same problem again this year.

Adam checked control room main power supply. I checked in TH crane again. The problem is still there. We can confirm this is the same issue like last year. 

Entry  Thursday, January 02, 2020, 09:55, David Wang, Cooling, Standard Operation, , , I turned on HALC water pump MP2. 

HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine.  Water level and system resistivity will be monitored for a while.

LALCW P5 and P6 are switched on  for cooling HALCW.  HALCW MP2 is in operation now.
