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. |

Friday, July 26, 2013, 11:06, David Wang, South Hot-Cell, Standard Operation, , , The steel shielding plug has been put on theSHC top in target hall
|
to reduce the radioactive shining from SHC Ta# 40 target. |
|
Tuesday, July 30, 2013, 14:42, David Wang, ITE, Standard Operation, TM4, , TM4 has been connected in ITE.
|
TM4 has been connected in ITE. All turbo pumps have been started now. The pumping down on TM4 and ITE is good so far. The water interlock check on TM4 is done,and everything is fine. The ITE IG1 still couldnt be turned on even if we replaced a new TM4 IG1 at CS. The problem is on the connecting cable from ITE to electrical room or gauge controller. I talked with Friedhelm and vacuum group will be noticed on this problem. |

Thursday, August 15, 2013, 07:37, David Wang, ITE, Repair, TM4, , I moved 5 shielding blocks from ITE to block storage area.
|
I moved5shielding blocks from ITE to block storage area, This is a job for preparing ITE vacuum surge investigation and leak check. |
Thursday, August 29, 2013, 06:48, David Wang, Conditioning Station, Development, TM3, , TM3 leak check in CS with new source tray. 
|
A huge leak had been found on HS circuit during 60 psi helium pressurize test. Other circuits are free of obvious major leak at present .We will test them again once the TM3 is back to CS. See attachment for details |

Wednesday, September 11, 2013, 09:35, David Wang, ITW, Standard Operation, TM1, UCx, 5 shielding blocks have been moved to ITW
|
I moved 5 shielding blocks to ITW this morning .I checked the water signals in electrical room before the moving, and everything is fine. The argon venting systemin ITW and electrical room is ready also. |
