Gas lines extensions installed yesterday were too long and gas lines touched top inside of containment box. They have been removed and the gas lines re-installed in their original manner. Gas lines have been "adjusted" as to clear the tube heater lines, which was the original issue. |

Ultem high voltage spacer installed and 9 pin banana plug plugged in. Target has been inserted into the hot cell and will be installed after base-line electrical checks...probably first thing in the morning. |

A few additional higher-resolution photos of the TM2 source tray with new spacer ITA6270, and bent copper ground line clip.
Also attached is a photo of a 3/8" copper line placed in between the loose ECR line and the Mounting Support Plate line, for dimensional reference. |

Electrical check done on TM#2 around the 25th of June 2015, this was before the coil line leak was found. |

Wednesday, July 22, 2015, 12:13, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Short Findings
|
Pin X was unplugged, short remained, however any slight pressure on the block towards the source tray makes the short go away.
Confirmed clearance between the EE and thr R / U coil lines as well as MSP of coil line.
Camera inspection would seem to indicate that ALL issues stem from a common location...there is a spot where both the pin X waterline and the one of the R / U waterline contact the heat shield waterline...one on one side of the heat shield line and the other on the other side.

|
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. |

Tuesday, August 11, insulator ITA6272 was installed onto the "pin x" line (unused plasma electrode) and tested; it seems to have successfully eliminated the shorts on that line.
Wednesday, August 12 "shunts" installed on tube heater and oven circuit and electrically tested.
Thursday , August 13, dummy target installed.

TM2 has been moved to CS. All turbo-pumps have been started. The pumping down is good so far. I connected the leak detector to service cap, and finished the leak check today. The LD base LR:0.0Xe-9atm.cc/sec. 80psi helium were applied to coil1, coil 2. HS and window circuits, each for 2minutes. No any response has been found on LD. So all water lines are leak tight now. I also sprayed helium to top service cap checking all air to vacuum seals. They are all good either. But, The new installed PGN1 does not work. Other thing need to mention is The TP2 is running at 2.45A which is 1A higher comparing to TP1. It need to be monitored to see if we have to replace it or not. The high current cables and water lines will be connected tomorrow morning. |

TGHT, TBHT, ANODE and COIL power tested (some amps/volts)
Monday, August 17, 2015, 10:43: BIAS/EL/EE to 15/7.5/1.5 kV
Monday, August 17, 2015, 10:45 : COIL 20A, ANODE 200V
Keiko fixed the auto-ramping program and access rights to it.
Monday, August 17, 2015, 13:06: Auto-ramping at 2/1 A/min. Good/bad vacuum at 6E-6 and 8E-6 T
Monday, August 17, 2015, 13:24 : ANODE current limit set incorrectly. Corrected and 200V (9 mA)

|
During the TM2 HV test at CS, It failed. In order to confirm there is no any water leak inside the module after the heaters and beam extraction test, I disconnected all the water lines on the TM2, and purged the water lines with pressure air. Leak detector was reconnected back to the TM2 service cap, and all water lines are pressurized with 80psi helium again each for 2 minutes.No any leak had been found during the test. All the water lines are still perfectly sealed. Also, I checked all the vacuum to air seals on the top of the module.They are good either. Anders used the RGA tracking the helium during the test. No leak. |

Thursday, August 20, 2015, 09:38, David Wang, Conditioning Station, Repair, TM2, , TM2 was disconnected at CS

TM2 was disconnected at CS. Travis and I did electrical check before the venting. After,The module was vented and moved to SHC. The moving is smooth. |
