TM2 was moved and connected in ITW yesterday afternoon. After roughing down, ITW turbo pumps are started. ITW TP4 can not be started to full speed. ISAC
ops kept it at low speed mode with less than 1.0A current draw on pump. ITW IG1s shows red as well. I will take a look on them today when beam is off.

Wednesday, March 23, 2016, 11:32, David Wang, South Hot-Cell, Repair, TM2, , TM2 Helium spray leak check on GE and MSP lines at SHC
|
Chad and I did the helium spray leak check on TM2 GE and MSP water lines at SHC this morning. We confirmed the GE leak on water blocks. We can
not found the MSP leak by using the helium spray since its leak rate in TCS is much smaller than GE leak. The leak check process are as below:

Monday, March 21, 2016, 10:25, David Wang, Conditioning Station, Repair, TM2, , TM2 Helium pressure Test Result in TCS and ITW
|
TM2 has been helium pressure tested in ITW and TCS. They are both tested with 70psi helium, each circuit for 3minutes.
The leak detector base leak rate: 0.0X E-9 atm.cc/sec, base pressure 0.0 xE-4 torr for both ITW and TCS. The test results are:

|
Spark between HV cover vertical mesh plate and HS 60KV bias connecting clamp 90degree angle at 55 KV on TM2 top. HV cover is removed to test above
55KV. The spark triggered TH and SHC ventilation secondary alarm. |

|
Starting HV tests on TM2 with 50uA of protons.
Tuesday, August 06, 2019, 03:37 : Ramping up 500V every 2mins or so, couple of sparks, then consistent sparks at 34kV. No vacuum response on IG1
for any sparks, even though the current spikes from around 40uA to 1300uA. Brought it down to 28kV to stop sparking. See a response on the EZL frequently. |

Thursday, November 01, 2018, 11:42, David Wang, Conditioning Station, Standard Operation, TM2, UCx 25., TM2 HS line helium pressure test at TCS and helium spray at SHC..
|
Chad and I did leak check on TM2 HS line at SHC yesterday. Base LR 0.0XE-9 atm.cc/sec. No response on LD. during helium spray.
Today , I did helium pressure test at TCS. base LR 0.0xe-9atm.cc/sec. applied 70psi helium for 3 minute. leak rate slowly climbed to2.2 Xe-7 atm.cc/sec
ate stopped there. The result is close to before. |

Wednesday, May 24, 2023, 08:34, David Wang, Conditioning Station, Standard Operation, TM2, TiC#6, TM2 HS line helium pressure check and gasline fittins leak check.
|
TM2 HS line helium leak check is done. leak detector base LR 1.8xE-8atm.cc/sec. helium pressure 70 psi. 5 minutes test. no change on LD leak rate.
I spray lots helium to gas line adaptor and fittings. No leak.has been found at this base leak rate level. Since the TCS MP1 has some
issue ,this time the base leak rate on LD only can get to 1.8Xe-8 atm.cc/sec at this moment instead of 0.0xE-9. The low E-8 level is not perfect, |

TM2 is now in the hot cell with the containment box off for inspection and eventual blank off off the water blocks.
Upon initail inspection the status (fron a hot cell point of view) is:
-Water block jig is equipped/on |

The containment box was taken off TM2 in preparation for installation of a new coil line isolator.
ITA6272 and ITA6273 have been received from the Scintillator Shop. ITA6274 should be ready by the end of today. |

|
First thing this morning the hot cell was "cleaned up" in preparation for the return of TM2 for attempted verification and locating of leak
on R/U coil circuit.
Containment box has been removed and front cover reinstalled to provide some modicum of shielding form the entrance and exit windows. Box was placed |

|
Firday, November 8 all water blocks (excluding I and K) were blanked off and vacuum leak checked. No responses were found. (First Picture)
I and K could not be blanked off without removal of the water block jig. Also, I dropped one of the blank offs onto the table, so one line could
not be blanked off until a new clean blank off was inserted into the cell. In addition, there was still reminace of a bolt in block Ias it aslo could not |

|
The water blocks soldered to the TM2 cooling lines (see Ref. Assy. ITA6144) were inspected.
See attached inspection reports and drawings.
It was found that only 18% of the seal groove diameters and 55% of the depths were in spec. |

Hello all,
TM2's first performance in the Conditioning Station with the new source tray was not great, with sparking and HV degradation beginning to occur |
