Entry  Monday, March 14, 2016, 11:24, David Wang, ITE/ITW Cooling, Maintenance, , , HALCW resin tank filter cartridges are changed today 002.JPG003.JPG006.JPG
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

Entry  Thursday, March 17, 2016, 14:57, David Wang, South Hot-Cell, Repair, TM2, , TM2 first round leak check in SHC 
Chad and I finished the first round check on Tm2 water lines.  The lines and spots checked are: Target oven + and - (front side braze  joints) , Tube
heater+and -(front side braze joints and water blocks),  coil2 and coil 1(front side braze joints and area close to water  blocks),. No leak has been found
on all above of them.  The last, we  checked   the GE which has the biggest leak so far. The leak detector  base leak rate only can get

Entry  Wednesday, March 23, 2016, 11:32, David Wang, South Hot-Cell, Repair, TM2, , TM2 Helium spray leak check on GE and MSP lines at SHC 
  Chad and I did the helium spray leak check on TM2 GE and MSP  water lines at SHC this morning. We confirmed the GE leak on water  blocks. We can
not found the MSP leak by using the helium spray since  its leak rate in TCS is much smaller than GE leak.  The leak check  process are as below:
