Tuesday, February 09, 2021, 13:43: DI water flow completely stopped.

Control room contacted. DI water loss confirmed.

Tuesday, February 09, 2021, 13:52: DI water flow returned.

Control room contacted. DI water loss due to a "seamless" pump change over for the DI water supply & mechanical services. The supply was transferred over to a new pump which overloaded and failed. They had to switch back over to the (old) pump. Mechanical services will still try to do the switch over again. Either tomorrow or the day after. Running the TS up to 580A until then is not recommended.  Control room to update tomorrow morning.

Hi Fernando,

  There are no plans for Cu-LCW system to be switched off today.  I believe they are still working on correcting the issue that caused the trip two days ago.  Once it is corrected and we are ready to switch to the secondary pump, the switch over "should" be relatively invisible with possibly a slight drop in line pressure.

 Thursday, February 11, 2021, 10:31: TGHT/TBHT at 400/200 A. Anode still at 10 V 

Thursday, February 11, 2021, 10:33: Auto-ramping TGHT/TBHT to 580/230 A @ 2 A/min

Thursday, February 11, 2021, 10:42: BIAS/EZL/EE @ 30/13/1.5 kV. 

Thursday, February 11, 2021, 13:42: Uncapable of holding HV. Maybe the new heatshield needs more time to outgas.

Thursday, February 11, 2021, 13:44: BIAS/EZL/EE @ 0.000 kV

Friday, February 12, 2021, 10:07: In order to trouble shoot the ISAC TS, I  let the sparks to continue. Initially, they occurred in the extraction electrode spark gap and were both visible and audible. However, they stop and the instabilitiy was present.

I rise the voltage again and let the spark happen for a longer period of time.

I saw how the collimator wire on the far back of the source tray was moving as if a hurricane was inside, which is very strange. I followed up the wire and I saw how it was sparking to something (see attached photo)

I say something because from the angle is difficult to say if it was going to the chamber itself or to the HS waterlines. Both scenarios are concerning

First of all the collimator is never biased and it if any case the jacket  (MHV cable) is on ground ground

In case the discharge happened from wire to the chamber, then the collimator wire was charging up, it is extremely important o note that the jacketed cable goes outside the box very close to one of the turbos.

In the other scenario where the discharge was happening from the wire to the HS waterlines, that is, HV to ground, the simply creating a clearance should be enough. In this case as well is relevant to know that this jackted cable leaves the farday cage.

I will create clearance from collimator wire to HS waterlines.

Friday, February 12, 2021, 10:33: BIAS/EZL/EE @ 0.000 kV

Friday, February 12, 2021, 10:35: Auto-cooling TGHT/TBHT to 0 A @ 4A/min.

Friday, February 12, 2021, 11:05: Discharge confirmed visually to go into the HS waterlines, (HV to ground) (see second photo attached)

Friday, February 12, 2021, 11:06: Inside the blue rack,  I could hear ticks that match the discharges, probably  the collimator PS is there. Will check later with things  off.

 Friday, February 12, 2021, 13:17: Turbos off.
