  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.

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.

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.

Chad and I finished leak check on HS line with UCx target installed on it.  Base Leak rate:0.0X 10^-9 atm.cc/sec, Base pressure 0.0X 10 ^-4 torr.  Sprayed helium to VCR joints.   No leak has been found . The line will be pressurized with helium at TCS.

 Helium pressure test on TM4 HS line is done at TCS. BLR 0.0XE-9 atm.cc/sec. 70psi helium , 2 minutes. No response. The line is leak free.

UCx#19 has been removed from TM4 and UCx#20 installed.

UCx#19 still had water in it at pressure and sprayed when the VCR was undone. It was quickly re-tightened but not before significant water pooled beside the main Mykroy standoff and table. Contacted Anders would suggested to soak it up with some wipes and continue, which I did.

New target fasteners including high current. High current fasteners torqued to 130 in lbs.

  1534   Friday, May 12, 2017, 07:42 David WangCraneRepair  TH crane burning smell, smoke, and big noise on east side main hoist brake assembly.

This morning, when I prepare for today's crane check, The crane made a very strong noise without any load during the full speed up motion. I stopped the crane right away, and noticed that east side of main hoist motor area was smoking . The crane was moved to east end. And, I climbed up to the top, and found the smoke is coming form brake side, and should be produced by braking. The smell is same as before.Unless other thing is wrong,  I think Gordon crane technician has to adjust the gap to a proper distance on both side of the main hoist. I feel very uncomfortable by operating the crane this way. They have to figure out what is wrong on these new brake assembly installation.

2017-05-12. This morning , Crane technicians increased both side of main hoist brake gaps today. They found on east side brake assembly, The gap is automatically closed after some  jogging motions. Peter think this is caused by torque produced by automatic adjustment springs on brake. This torque rotate  the gap adjustment device and closed the gap.  We operate the crane for a while with 20000lbs load on it after gap adjustment. The rattling sound is still there at slow up motion.  But, The main hoist braking sound is softer and gentle comparing to past month.This sound is more close to the sound before we replaced the brake assembly. So, This adjustment could be right in my view.  They checked  gaps after 0.5 hours operation. Everything is still fixed there . No change. They suggest we keep operating the main hoist, and they will be back on next Monday check again.  I operated the main hoist up and down in different speed motion for 1 hour after they left. Everything works fine. Braking are gentle. No strange sound and smoke during up or down. I will do  more operation on Monday morning before they come. Lets see the result after their checking.  

2017-05-15 This morning, 20minutes of crane main hoist up and down test with lots jogging and braking. The braking sound is softer and gentle. Everything works fine.

2017-05-15.  Gordon crane technician Peter came in during lunch time. Both side main hoist brake gaps have been checked. They are still at the same position as last Friday. The gap is not changed after operation. Peter will be back on next Monday and check everything again.
