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 |
Friday, August 21, 2015, 11:38, Anders Mjos, South Hot-Cell, Repair, TM2, FEBIAD Test Target, Steerer wires found to be touching the gas lines
|
Yesterday TM2 was inspected in the SHC. Spark marks were found both on the steerer wires and on the ANODE wire. The steerer wires (GND) were touching
the gas lines (60kV). This is likely the cause of the sparking observed at the Conditioning Station (e-log).

|
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 |

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 |
