  1540   Wednesday, May 17, 2017, 08:35 David WangConditioning StationStandard OperationTM4 TCS turbo pumps was started yesterday

Anders started TCS turbo-pumps yesterday. The TCS and TM4 pumping down is good so far. I started TCS water pumps this morning for TCS water flow check.

2017-05-17 morning:  Stopped the water pumps. The field around the TM4 is high because of spent target in SHC. The water flow measurement will be delayed to this Friday.

  1541   Thursday, May 18, 2017, 10:08 David WangConditioning StationStandard OperationTM4 TM4 TP1 at TCS

TM4 TP1 was found making some noise during operation this morning. The current draw was check then. It was 1.8 A which is higher than 1.0A normal range. The pump body temperature was higher by hand feeling. But,1.0 hour later when checking again, everything on the pump goes back to normal. It is still fine so far. I will watch on this pump closely.

 2017-05-19,morning.  The TM4 TP1 stopped running last night.  I tried to start it this morning. But, It can't pass 6KRMP even. I think we have to replace it.    E- fault will be issued as well.

TM4 TP1 is replaced. TCS and TM4 was argon vented before the job.The job took about 30minutes.  I started the all turbo pumps after job. All pumps work fine. The TCS vacuum is good.

We do this check once a year now. Rene found a target oven reset issue during the check . He will consult with Friedhelm. The interlock check is good.

  1553   Thursday, June 08, 2017, 07:37 David WangConditioning StationStandard OperationTM2 Helium pressure test on TM2 water llines at TCS.
  The helium pressure test on HS line is done at TCS this morning. I got the same result as last time when we helium pressure it it with first target in April. The leak  rate on this line is 1.8 XE-7atm.cc/sec. So, we know this leak is mostly on the line, but not on the VCR joints connecting the target.  See attachment for last time(April) checking e-log. The leak could be from water block which is same as other lines. I do not think this leak rate will affect the operation.

The attachment can not be opened for some reasons. Please check TM2 leak check  2017-03-13 e- log for last time test result and comment.

Reconfigured TM2 gas line on the module top. It matches with the febiad gas line we are using on service tray now. Facing the module, both of them should be that right side line of two SST lines on feed-through. The gas line on TM2 was leak checked with a blind cap installed on service tray side and LD connected on module top this Tuesday. It is leak free with helium spray on the top of module and service tray.

Yasmine and I connected TM2 in ITW today. the control page is set to febiad mode. Both gas line in ITW are opened for febiad run. All connections are double checked. Module connection checklist is finished.  All turbo pumps are started now. Everything is good so far. The TM2 is ready for conditioning when the ITW vacuum is good enough.

Gordon crane technician Peter came in today and checked TH crane. Maico and I were there with him. What he found is that brake gap on both side of main hoist decreased after months of using.  The solution is to lock the automatic self adjustment system so the gap will be fixed there. Each year during annual inspection, they will adjust the gap manually. After he locked both side of device, I tested the crane up and down couple of times. The brakes work fine.
