Wednesday, July 17, 2013, 08:29, David Wang, Conditioning Station, Development, TM3, , TM3 leak check in CS without source tray.
|
Leak checked TM3 without source tray in CS this morning. The CS and TM3 vacuum: IG1(top of the TM3 service cap)4.9x E-7Torr, IG2(diagnostic box primary)1.9XE-6 Torr. IG1S (secondary vessel)7.9X E-7Torr. The leak detector was at 0.0XE-4 torr and 0.0XE-9 atm.cc/sec level during the leak checked. All water lines quick connector fittings, NPT thread fittings, water cap seals, blue insulator seals, bellow, gauges seals, turbo-pumps, all blanket panels,and TM3 to CS vessel seal have been sprayed with helium and leak checked. No leak has been found. The TM3 is leak tight in CS. |
|
Wednesday, July 17, 2013, 10:10, David Wang, Conditioning Station, Development, TM3, , CS cooling and vacuum system have been turned off
|
CS water cooling and vacuum system have been turned off at 10:00 AM this morning.The TM3 will be disconnected and moved to silo tomorrow morning. |
|
Wednesday, July 24, 2013, 17:46, David Wang, Conditioning Station, Standard Operation, TM4, Sic 29#, Started 3 turbo pumps on CS for TM4
|
3 turbo pumps on TM4 and CS have been started. The pumping down is good so far, The TM4 PNG1 reading is more than 10 times higher than IG1 which is at the same chamber. It could be a controller problem. Other 3 high vacuum gauges behavior normal. The TM4 IG1 is replaced today and it works fine now. |
|
Thursday, July 25, 2013, 10:08, David Wang, Conditioning Station, Standard Operation, TM4, SiC #29, TM4 HS helium pressure test andTM4 connection at CS
|
Bevan and I did a helium pressure test on TM4 HS water circuit at CS. The leak detector is pumped to the bottom scale(E-9 atm.cc/sec and E-4torr). We applied 70 psi helium to the HS circuit for 3 minutes . No response had been found. I also leak checked IG1 flange which was replaced yesterday. It is good. We connected the TM4 to CS and put the HV cover on. The water cooling system will be started soon. |
