Connection of TBHT negative to HV common removed (R4 in circuit diagram). Labelled and put in MRO bucket.

Anode connection moved to feedthrough J.

Rewired multipin patch panel. Left some grounded (HVC) wires hanging, should probably make this nice later.

Tuesday, December 01, 2020, 11:56 :

TSG:BIAS unplugged and controls pigtail (made by Ray) added in order to connect controls cable to TCS:BIAS, which is now installed in the same rack.

Basic controls testing done without turning on the power supply, controls max values scaled to 75kV, 5mA.

In process of grounding all features inside the faraday cage. New grounding will be marked with a label for easy identification later.

NOTE: we should get together in January to discuss test stand wiring, since I discovered another burned up connection (see next elog entry, #823).

Tuesday, December 01, 2020, 16:47 :

Grounding of all feedthroughs on the service cap complete and continuity checked.

Removed gas line with Fernando's approval, to make more space for our feedthrough.

Awaiting nylon insulator to proceed.

Wednesday, December 02, 2020, 08:31 :

Added copper wire connection to multipin screw terminals in HV cage to make sure they are grounded.

Attached grounding rod to back of HV cage. Not ideal, but couldn't find a better place without making a extension to the cable. Will see what John Chow says. EDIT: John says it is ok for the tests, not for permanent.

Vented test stand to swap window positions. Swapped rightmost window on the door with two windows with window on the door with only one window. Replaced one oring, that on the single window. Cleaned the inside surfaces of both windows with methanol before re-installing. Roughing down just to make sure there are no major issues, at 0.313T and falling. EDIT: down to 0.015T overnight.

All breakers on HV cage panel are OFF.

Friday, December 04, 2020, 08:52 :

Test stand roughed down to 29mT overnight. Started turbos for testing later.

The copper tubes to be used in the TM3 test piece may have flux inside them from soldering the end caps on. There are holes along the length for outgassing, and we will try to bake them out in the test stand before installing them. There is still a dummy bake out target installed there, see the photo for how the tubes are loaded in. TGHT ramping started around 3pm.

I had to remove the grounding connections from the TGHT feedthroughs for this, so I redid them such that the tube is attached to the EZL. This target has no tube, so the connection between the tube and target is just through the 100Ohm resistor.

We must re-do the grounding before proceeding with HV tests.

Wednesday, December 09, 2020, 19:38 :

Target heater ramp down started. See attachment for vacuum progression during bake out.

Test piece installed with Sam, Aaron and Alexander. Ended up shimming the support stand (middle foot) since it seemed to be bowing a bit and distorting the gap between the containment box stand-in piece and the service tray piece. We should measure the gaps when testing is done with the same configuration. Installation was not too hard, installed the whole thing as one piece. Had to remove the middle foot on the long side to get it through the door but otherwise no problems.

Test stand re-wired for HV testing. Wire hooked up to test piece by pinching between two tubes. Verified GND and HV continuity.

Thursday, December 03, 2020, 15:54 :

Got sign off from John Chow to run the system, though the nylon insulator was not ready when he came by. But we went over everything together.

Installed blue nylon insulator with all vacuum surfaces cleaned at least with methanol. No NPT fitting or tube installed, just testing service cap.

Thursday, December 03, 2020, 17:31 :

Tested voltage on the blue nylon insulator up to 75kV, left it at 75 for ~30mins. No sparking, no current drawn except occasionally when changing voltage and only ~1uA then.

Cleaned (but not very well...) the NPT fitting, copper tube, alligator clip and section of copper wire and installed these in the vacuum chamber. Will pump down overnight for testing tomorrow.

See attached photos for insulator setup and wire inside vacuum chamber.

See elog 737 

Thursday, June 27, 2019, 09:45: The cables showing burnt marks were changed with new ones on Wednesday 26th. The grounding cables were insulated with yellow heatshrink. The anode wire connection was redone.
