|
Anders and I opened the HV cover in ITE and did a visual check inside ITE HV cover and top of TM3.Bill was with us and took the pictures.
There was nothing obviously wrong when we opened the HV cover in ITE. We disconnected TM3 high current cables from ITE. Then we did an electrical check
on TM3.The TM3 was good and passed megga test (465Mohm at 500V). The module was good and was separated electrically from the ITE at that moment. Then, |

|
Friedhelm Ames commented to me that there appears to be a short between High Voltage and Ground at TM3 at ITE.
Friedhelm, Anders and I initiated a survey by Andrew from RPG, and entered the Target Hall at approximately 5pm to visually assess the HV cover
at the MAA. There was no clear indication of a problem. We opted to wait for David to return as we weren't sure exactly what we were looking |

Wednesday, May 07, 2014, 10:15, David Wang, ITE, Repair, TM3, , ITE TM3, entrance module and BL2A3 window flange seals leak check..
|
ITE TM3, entrance module, and 2A3 window flange seals have been leak checked this morning after 2 new seals replacement.The LD base leak rate was 0.0xE-9
atm.cc/sec, base pressure was 0.0 XE-4 Torr. I sprayed lots helium around the TM3, entrance module and 2A3 flange seals. No any response had been
found on LD during the spraying. All three flanges are sealed perfectly now. |

Helium leak checked 2a3 window after installing using remote line:
- There was a leak found between the target and entrance module at the target pit, rate of 9E-6 atm-cc/sec.
- One test performed with the remote helium line to the window. There was a response but the leak detector was located above the window access |

|
David W. has installed two SST Proteus flow meters, model OV7006FTA32, on ITW Heat Shield and Coil. The flow meters are connected to a power supply and
a data logger in the electrical room.
The Heat Shield flow meter has SN 00278112 and is on the Black wire pairs and connected to CH3 & CH4 on the logger. |

|
The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that
reset the bias PS and another one after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting
the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem. |
