TM4 has been reconnected to ITE after the module moving. The roughing is started . The water will be supplied to ITE after testing the water
pumps . The water interlock check will be done on next week also. |

Wednesday, March 27, 2013, 12:08, David Wang, South Hot-Cell, Standard Operation, TM4, Sic LIS-RFQ, TM4 heat shield circuit leak check with SiC LIS-RFQ target
|
Chad and I did the TM4 heat shield leak check yesterday at SHC. The leak detector was pumped to 4.6 xE-9atm.cc/sec, and 0.0xE-4 torr after 1.5 hours
pumping. Chad sprayed helium twice on both VCR fittings. There is no response had been found during each 45 seconds waiting time. Since the module moved
to ITE directly,we didnt have helium pressure test this time. I would say thee heat shield circuit is leak tight. so far. |

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. |

|
TM 4 had been leak check in ITE due to relatively high PNG1 and IG1 readings.All TM4 primary and secondary vessel air to vacuum seals had
been leak checked. All water lines in TM4 had been helium pressured . There is no leak had been found so far. |

|
Initial Summary:
TM3 sparking behaviour in ITE has been very disruptive both with and without protons. Protons are at 60uA, target heater at 540A. Max voltage achieved
so far is 51kV, limited by time and a current limit on the BIAS supply. |

|
SiC#46 loaded into pail 293 successfully along with other hotcell waste
Upon visual inspection of the target, a spark-sign was spotted on the perimeter of the extraction electrode. Metallic looking material also found
built up between the extraction electrode and the backing plate of the target |

SiC#46 (pail 293) was placed in the vault (spot 3B) on Wednesday the 14th of August. It was 111 mSv/hr when removed from the south hot
cell. See attached PDF for details. |

|
Looked at SiC#45 in the hot cell. Looked very clean, no deposits on the heat shield or other components. Target also looked very straight. Only issue
we saw was sparking marks on the EE side that faces the ground electrode, in several spots. This target had a bout of sparking when ramping up the protons,
so I guess that was the location. Will look for matching spark marks on the ground electrode next time TM4 is in the hot cell. Forgot to take picutres... |

|
TM4 with SiC#44 installed developed a short TBHT to HV common during its first heating in ITE. Was fine before installation. Now with everything cold
TBHT to HVC is 25kOhms. Removed short in electrical room, will rely on short in the module. |

Spent target move done. The SiC#44 was moved from the north hot cell to the spent target vault. It was placed in pail#275 and placed in spot#4A.
It was 42.6mSv/hr when removed from the north hot cell. See attached PDF for further details about the vault.
Please note we will only have two free spots in the vault at the start of the |
