Wednesday, April 05, 2017, 14:13, David Wang, Conditioning Station, Maintenance, TM1, , TM1 and TCS vacuum system are connected together
|
| I started two turbo-pumps on TM1 and one small TP on TCS. They are work fine. |

Friday, April 01, 2016, 14:41, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 and TCS vacuum system has been connected. TCS control page white out.
|
I can not start the TCS pumps due to control page white out. Control group is working on this issue.
Control group fixed the white out problem. I started all turbo-pumps. The pumping down is good so far. The TM1 IG1 is broken. I will check it on
next Monday. It could be a broken filament. Then, the filament will be replaced. |

|
TM1 air to vacuum and water lines leak check at CS are finished this afternoon. The leak detector is hooked directly to TM1 service cap so the
base LR at LD is 0.0xE-9 atm.cc/sec. I sprayed helium to all air to vacuum seal on the service cap, also applied 70 psi to all water lines(except HS) for
2 minutes each. There is no any tiny response had been found on LD. So All TM1 water lines(except HS) and air to vacuum seals are leak free. The HS circuit |

|
Vacuum leak check on the window line circuit of TM1 took place yesterday and again to confirm this morning. Both days the response to helium is in the
area of a soldered reduction fitting at the top of the containment box above and to the shutter side of the extraction column (see attached picture). To
verify this morning each joint in the system had a 1 second shot of helium and then timed for 1 minute to wait for a response. This area responded both |

|
Replaced the custom silver gaskets on the entrance window panel of TM1 this morning...this has eliminated an sign of leak at this joint, however there
appears to still be a leak somewhere...a good distance from the vcr joints of the window as we are getting a drift response.
Chad sprayed helium to soldering stems in containment box which we suspected with leak last week. With 1second click on helium, after 80 |

Thursday, August 02, 2012, 07:48, David Wang, Conditioning Station, Standard Operation, TM1, UCx, TM1 UCx target heat shield helium pressure check is done.
|
Connected leak detector to TM1 and CS vacuum system. The vacuum readings on TM1 and CS:PNG4 3.6 xE-6 Torr, IG1 1.1xE-6torr, IG4(diagnostic box) 3.4xE-6
Torr. Leak detector base pressure:0.0xE-4 torr, base leak rate: 0.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 4 mins . There
is no response on leak detector. The heat shield circuit is leak tight. |

Thursday, November 08, 2012, 08:42, David Wang, Conditioning Station, Standard Operation, TM1, TiC #3, TM1 TiC #3 target heat shield helium pressure check is done.
|
TM1 TiC #3 target heat shield helium pressure check is done at conditioning station. Applied 80 psi helium to HS circuit for 5 minutes
. There is no response had been found on leak detector. The leak detector base LR 0.0x E-9 atm.cc/sec, and BP 0.0xE-4 torr. CS and TM1 vacuum are at low
E-6 torr range. The HS circuit is leak tight. |

Thursday, September 20, 2012, 09:16, David Wang, Conditioning Station, Standard Operation, TM1, Nb#7, TM1 Nb#7 target heat shield helium pressure check is done.
|
Leak detector pumped down to base LR1.3xE-9 atm.cc/sec, and BP 8xE-3 torr. All high vacuum gauge readings at CS and TM1 are at low -6 range from 1.2xE-6torr
to 4.6x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit
is leak tight. |

Over the period of July 20-21st TM1 had several repairs completed and tested. The easiest of the repairs was the installation
of a gasket and a blank off. The next repair was to replace the 2 oring on the side panels that were removed for inspection and repair. The instrument
panel oring was replaced again and the previous one measured. Both were found to have the correct diameter of 0.131 inches for the seal groove. When attempting |

|
TM1 has been connected in ITW . The new roughing pump replaced on last Friday works good. I started all turbo pumps in ITW. The ITW TP1 controller
was broken during the starting time. Dimo and I changed a new controller for ITW TP1 in electrical room. The pumping down is good so far. ITW water supplies
to TM1 only. |
