|
I replaced flow wheel and coil on ITW MSP water flow sensor which is located in ITW pit. Before replacement, I checked the signal strength and frequency form e-board on this circuit. The signal was good in 10minutes watching. Still, I replaced them. The flow sensor works fine after replacement. I made a comment on Isac e-fault system about this issue. |

Thursday, November 06, 2014, 08:55, David Wang, ITW, Repair, TM1, ThO#1, primary vacuum back up pressureITH CG1 ,CG2,CG4A were high.
|
I found primary vacuum back up pressure ITH CG1, CG2, and CG4A were unusually high this morning. They should be about 10 -20 mtorr after one night pumping, but all of thier reading were 340-350-mtorr. Thease cause the current draw on primary turbo pumps were all over 2.0A(should be about 1.0A). I let Paul closed all BVs on primary side . The pressure dropped quickly to normal range after all BVs were closed. This shows the back up line are good. The problem are from one of the connections on primary BVs. I let Paul opened the BVs one by one,but the problem did not show again. Now ,the current draw on the turbo pumps are back to normal also.
I will keep monitoring the system and take a look on all KF25 clamps on BVs once I have a chance to access to ITW. |

Tuesday, November 04, 2014, 11:05, David Wang, South Hot-Cell, Standard Operation, TM1, ThO#1, Leak check on TM1 HS water line withThO#1 installed.
|
Chad and I leak checked HS line on TM1 with ThO#1 target installed. The LD pumped down to base leak rate 0.0xE-9 atm.cc/sec, base leak rate 0.0xE-4 torr. The pumping down process is normal. Chad sprayed helium on both VCR joints (each for 2 seconds) , and he did a flush spray around the target for 5 seconds. No any response had been found on LD during and after the spray( 40seconds waiting time). The target is leak tight. |

TM3 TP2 stopped working this morning at 4:00 AM. I tried to start it but failed. On normal start mode , It could not pass 6K RPM. On soft start mode , the pump cant pass 17KRPM. Talked with Anders, We are not going to replace this pump since we are not going to run this module for a while. I will stopped all vacumm pumps on CS and TM3 this morning. |
