Two of resin tank filter cartridges(supply and return) are changed today. Old cartridges and bagged and tagged. The contact field on them are 650usv/hr.
The new cartridges are fiber-glass, Triumf store item. After replacement, the field on contact with the filter case are about 10 usv/hr. But the field
on contact with top resin tank has been increased from 45usv/hr to 225 usv/hr |

Friday, March 04, 2016, 12:34, David Wang, ITE, Standard Operation, TM4, , TM4 ITE annual leak check
|
Dan and I finished TM4 and ITE annual leak check on primary and secondary vacuum vessel. We found one leak on a KF25 blank off which is located
on the top of the service cap. It is a low E-7 atm.cc/sec range leak. But, it is very close to turbo-pumps so ITE IG1 and other gauges are not affected
by it very much. It is an easy fix. TheKF -25 center ring on the blank off will be replaced after vent . It be will leak checked again at CS |
|
Wednesday, March 02, 2016, 10:04, David Wang, ITW, Standard Operation, TM2, , Leak check on ITW and TM2.
|
Dan and I leak checked TM2 and ITW primary vacuum vessel. It was found a 1X E-7 atm.cc/sec leak on top T flange seal between TM2 and dump module in first
time check. But it is not a repeatable leak. I checked the same spot and around area two more times with increased helium volume.It did not show up again.
The first response could be a helium drift to dry scroll pump. I will check it again later. The primar vacuum vessel on ITW and TM2 are leak free. |

It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did
not correspond to local values displayed on the controller. An e-fault has been submitted. |
