Friday, May 05, 2017, 11:53, David Wang, Conditioning Station, Repair, TM3, , sparking on TM3 serice cap top.
|
Sparking was found this morning inside HV cover on TCS in TH while TM3 was HV conditioning at TCS. The TCS bias was set to 50KV when I found this spark.
It sparks between HV cover front side wall to a KF 25 clamp on HS water terminal. The KF 25clamp is used in this situation on HS water line top because
the HS line is opened inside module, and we need a vacuum seal on the top of this line. Actually, The clap is much smaller than the corona ring on |

Source tray is complete for brazing, gas line bracket is currently missing but can be made in parallel with tube bending operations.
Source tray water lines to be fabricated according to ITA6144 drawing set.

Wednesday, March 29, 2017, 14:11, David Wang, Conditioning Station, Standard Operation, TM4, , small leak on TM4 Ta(-) water line.
|
A small leak has been found on TM4 Ta(-) which is marked as "B" on terminal blocks. The LD base Leak rate is 1.2XE-8 atm.cc/sec. 70psi helium
has been applied to Ta(-) water line for 3minutes. The leak rate went up to 2.5xE-6 atm.cc/sec and stabilized there. Anders found a helium response on
RGA helium reading during the same time. This confirms the leak is real. Other lines are leak checked today also. They are good still. All TM4 water lines |

Sunday, August 11, 2024, 11:25, Carla Babcock, South Hot-Cell, Repair, TM3, TiC#8, short on multipin wires to TBHT discovered
|
With the new TiC#8 target installed on TM3, there was a ~7kOhm connection between TGHT/TBHT (A/B/C/D) and HV common. The standard electrical check on
the module showed standard values, so it was assumed the problem was inside the target.
Started removing bolts/water connections one by one to see if any of them had an effect on the measurement. Found that disconnecting the multipin |
