  1080   Thursday, September 24, 2015, 07:00 David WangConditioning StationMaintenanceTM4Ta#46Turned off TCS all vacuum pumps and water pumps.

TCS:MP1 back up pressure went up too high (700mtorr).I turned off all the pumps.The TCS is under vacuum still. TCS water  package cooling fans showed error on control page.The water pumps are stopped  also.

Restarted the vacuum pumps 40 minutes after stopping. Everything is back to normal. The MP1 back up pressure need to be monitored frequently before we have a final solution on this issue.

Reset the CS cooling package on roof and restarted the water  pumps. The system is running good so far.

Chad and I leak checked TM4 HS water line with new Ta#45 target installed at SHC. Leak detector base leak rate 0.0Xe-9 atm.cc/sec, base pressure 0.0Xe-4 torr. Chad sprayed helium twice on each of HS 2 VCR joints.No leak has been found. The joints are leak tight. The helium pressure test  will be done at CS later.
