Saturday, December 03, 2016, 10:01, David Wang, ITW, Repair, TM2, , venting ITW and TM2 with argon.
|
A short between TM2 EE and bias is produced yesterday during tube heater ramp up. Alex asked for an argon venting on ITW to see if the problem
could be solved by venting and pumping down yesterday. I set up argon venting system in electrical room and started the venting at 8:30 AM this morning.
It will take 5 hours to vent the ITW to 760 torr(mechanical gauge reading). The venting system pressure is set as 2 torr. A pressure relieve valve |

Monday, December 05, 2016, 10:10, David Wang, ITW, Standard Operation, TM2, , Five shielding blocks have been transferred from ITE to ITW.
|
| The ITW is configured to take proton beam. |
|
Wednesday, January 04, 2017, 14:27, David Wang, Conditioning Station, Standard Operation, , , started TCS vacuum pump
|
TCS TP1S has been started.
2017-01-23 afternoon: Stopped TP1S. We will use TCS to take TM2 tomorrow afternoon. |

Thursday, January 12, 2017, 14:24, David Wang, ITW, Standard Operation, TM2, , ITW primary and secondary vacuum vessel winter shut down leak check.
|
TM2 is located in ITW for this leak check. Leak detector is installed between ITW BV2s as before. LD base leak rate 0.0XE-9atm.cc/sec, base pressure
0.0XE-4 Torr. First , I leak checked dump module top flange seal which a small leak was found in last year winter shut down. This time,all ITW turbo-pumps
cooling fans are switched off during the check. Lots helium are sprayed around the dump module top flange this time. I did not see any response on LD. |
|
Monday, January 16, 2017, 09:32, David Wang, ITW, Standard Operation, TM2, , Helium pressure test on TM2 water llines at ITW
|
TM2 helium pressure test result at ITW. 70 psi helium 3 minutes on each circuit. LD base LR0.0XE-9atm.cc/sec BP 0.0XE-4torr. ITW IG1 1.22Xe-7
torr, ITW IG1S 1.31XE-7torr, ITW PNG4 2.66XE-6Torr(ITW TP4 off).

Wednesday, January 18, 2017, 09:55, David Wang, ITE, Standard Operation, TM4, , ITE and TM4 2017 winter shut down leak check.
|
ITE and TM4 2017 winter shut down leak check are finished. All ITE primary, secondary vacuum vessel and TM4 water lines are good. No any leak has been
found. |
Thursday, January 19, 2017, 10:15, David Wang, Conditioning Station, Standard Operation, , , Target Hall schedule for 2017 winter shut down 
|
Updated target hall schedule for 2017 winter shut down. See attachments 1,2
Update schedule after Febiad beam schedule changed to ITE. See attachments 3,4 |
|
Tuesday, January 24, 2017, 15:24, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 electrical check and leack check.
|
I did electrical check before and after Fefiad target installation on TM2. The RU (coil) Is till short to 60KV as before. Other result are good. After
Febiad target is installed, Tm2 HS line is leak checked. On leak detector, base leak rate pumping down is much slow than before. The base pressure
still could be pumped down to 0.0XE-4 torr. After a long time wait, Chad and I leak checked at 2.2XE-8 atm.cc/sec base leak rate. Chad sprayed lots |

Tuesday, January 24, 2017, 15:29, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved to TCS .
|
| I connected TCS vacuum system to TM2. The station is under roughing now. All turbo pumps will be started soon. |
|
Tuesday, January 24, 2017, 15:32, David Wang, ITW, Standard Operation, TM2, , TM2 was moved from ITW to SHC this morning.
|
| The move is smooth. Yasmine and Travis did the move. |
|
Friday, January 27, 2017, 10:52, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 has been moved from TCS to ITE
|
| The move is successful. |
|
Wednesday, February 01, 2017, 12:23, David Wang, ITE, Standard Operation, TM2, , TM2 has been connected in ITE.
|
TM2 has been connected in ITE. The SST window water lines in ITE can not be connected properly to TM2. The water line connector on TM2 window is 90 degree
CCW installed in direction comparing to TM4.This caused the problem. Solution: Two piece of flexible lines and extra male QC adapters have been used to
fix this issue. HV cover and HV fence in ITE work with TM2. Other connections are good as well. |

Tuesday, February 07, 2017, 10:34, David Wang, ITW, Maintenance, , , ITW clean up
|
ITW has been cleaned up today. All station are vacuum cleaned. I wiped all HV cover and HV area including conductors and insulators. The black
foams which are used to wrap around TP back up line are degrading now. I removed most of these foams. Also, Some obsolete water lines are moved
our of station. All waste are bagged . they will be surveyed and stored(or disposed) according to radio-active level. |

Thursday, February 09, 2017, 09:24, David Wang, Conditioning Station, Development, , , Target module window cooling lines at TCS.
|
Target module window cooling lines at TCS has been modified to use spare 2 channel in TCS: WFB1. The old cooling lines used a spare channel in
TCS WFB2(HVC channel) are removed and capped. After change, TCS window cooling lines will be interlocked with heaters. The test run on new lines are good.
No leak on all fittings, and signals on flow and temperature are good. Control people will be noticed on this change for their following up |
