Monday, February 01, 2021, 14:04: HV turned itself off, nothing tripped nor change. Not sure if related to the emittance scan that I was running. Setting it to zero before restarting it.

Monday, February 01, 2021, 20:14: Ramping things down and call it a day. My laptop charger broke and I don't want to leave the HV on.

Wire scanners look fine but the emittance meter was not working. Keiko soft reboot it but to luck.

 FM

Wednesday, February 03, 2021, 13:01: Spark. The HV bias voltage remained at 10 kV for several seconds. TSG:CBC was @ 2500 V. Likely, a sustained discharge towards the steerer had the HV bias power supply to get current limited

 Wednesday, February 03, 2021, 13:25: HV bias power supply gets current limited as of 15 kV. Setpoints to 0 to allow some discharge. Didn't work. Asking someone on site to have a look on the PS.

No sign whatsoever of a spark  to any device.

Wednesday, February 03, 2021, 18:27: HV has been erratic all day. Waiting for some stabilization allowed the system to reach ~24 kV. Now it has dropped to 20 kV.

Wednesday, February 03, 2021, 18:28: Increasing current limit on the bias PS from 0.015 to 0.02 mA

Wednesday, February 03, 2021, 18:55: Spark in the water lines. Current drop 60% from 0.03 to 0.01 uA. Spark observed in the GND electrode water lines

Wednesday, February 03, 2021, 19:11: Able to reach 28 kV but a spark ocurred.  TSG:CBC adn TSG:Q1 readback 2500 and 1500 V (similarly to the spark at 1 pm). Bias is current limited again, even at the new current limit.

• I think there might a short with one of the steerers cables, or a bit unlikely, to the quad.
• Slow charge up process, that does not discharges.

Thursday, February 04, 2021, 14:39 : Small bright spot at the TGHT or HS cooling lines from the solder of the GND water lines.

Without voltage this is not noticeable. Likely a corona discharge happening at this location and hence limiting the current.

Sunday, January 31, 2021, 16:11: Things were looking good so i  decided t o try  a mass scan , however a series of sparks started. I set all biases to 0 and stop the tests for today.

Friday, January 29, 2021, 09:11: CANBUS controller was replaced. Quick systems check ok. Sources, HV, & Optics all good.

Friday, January 29, 2021, 10:05: HV & Ramping check.

Friday, January 29, 2021, 10:08:

The system was vented to  make clearance on the waterlines as a very small continuous discharge was observed.

The inspection revealed some marks on the HS water line (sideview photo). From the the bottom and from real close (zoom and backview photo) the marks are quite noticeable with shinny copper in the middle and dark circles around.

The GND line is routed in such a way that sits on top of the ion gauge chamber (gnd-ig1) this could explain why the vacuum had small oscillation during the current limited events.

Moreover, the GND line has the steerer cables tied to it, this could explain why one of the steerers got affected after the sparks.

Also, the GND line is in contact with a dark grime that goes all the way into the first skimmer (gnd-quad). I think the grime observed inside the test stand might have become conductive, or if this is trace from a previous flashover, this  is good path to flash again.

The EE and the plasma electrode were removed and they show signs of buildup. Cleaned and reinstalled

Re-salted. PE removed. EE Cleaned

 FM.

After inspecting the ion source, and revising the electrical connections, I suspect that the TBHT was floating all the time and only when it was in contact with the plasma electrode it held HV.

When the plasma electrode was removed, there was no reference whatsoever, and the ions were not extracted.

It seems then that the resistor R4 (ISK4562D) is necessary to provide a reference to the TBHT  in a similar way R1 provides one to extraction electrode.

Tuesday, February 09, 2021, 20:52: Installing R4. If the anode works this time, it will be worth checking why this reference is necessary. From the electric diagram, the chassis ground should be HV ground.
