|
The wiring on the top of the test stand was burned, see entry 737.
Probable cause of this is as follows:
Coil lines are connected by a wire to HV common, the 9-pin feedthrough etc to maintain same voltage on all the insulator tops. This is also directly |

|
Tuesday, June 25, 2019, 16:15: While inspecting the 9-pin connection with Ferran, it was noticed how two braided cables were burnt out pretty bad to
the point they were separated in half (see attached pictures). Additionally the plastic insulator for the anode wire was melted.
Tuesday, June 25, 2019, 16:30: Braided cables need to be changed and anode wire redone. |

I opened the test stand because I forgot to install tantalum heat shields around the target. Everything was reinstalled as before (with heat shields).
I could turn on the TSGTP1B but TSGTP1A does not turn on for some reason. I tried multiple times opening/closing its valve (BV1A) but the pump never starts.
Will keep pumping over the weekend with TP1B only. |
