Aurelia has been testing on the ISAC TS since last week. Thermocouples are installed in the end cap, left side & the ionizer.

No elog was initiated, but much has happened.

Tuesday, November 28, 2023, 09:28  after pumping over night IG1 is at .15e-6 T. Water cooling on.

Tuesday, November 28, 2023, 14:34  HV test started. Sparks on the TC seen at BIAS/EE/EZL 31/-1.8/15kV. TC values recovered after sparks, TP6 tripped during sparks as well. Venting chamber to reposition TC.

Tuesday, November 28, 2023, 17:37 I couldn't manage to close properly the side door of the chamber... waiting for help tomorrow.

Wednesday, November 29, 2023, 10:51 Roughing started earlier in the morning. IG1 at 1e-5 T. Ramping up bias.

Wednesday, November 29, 2023, 11:41 HV tests lead to 45kV sparks on the TC. Nothing seen on the RPi.

Wednesday, November 29, 2023, 13:22 The ballast of TMSRP2 was opened to attempt to improve the roughing in the beam line section. Things appear to be somehow better now, TMSTP6 and TMSTP2 are on now.

Wednesday, November 29, 2023, 16:00 IG1 is at 3.58e-6. HV tests starting again.

Wednesday, November 29, 2023, 23:36 HV tests ended earlier in the afternoon. No spark up to 55kV when gauge in the HV cage started sparking as usual.

Wednesday, November 29, 2023, 23:38 TGHT and TBHT ramp up in preparation of mass scans in the morning. 1A/30s up to TGHT:400A, TBHT:160A

Thursday, November 30, 2023, 12:12 Mass scans started earlier in the morning. 1st scan completed at 0.1A/s, repeating it again now with 0.05A/s.

Thursday, November 30, 2023, 15:04 HV tests again up to 55kV. 2 sparks inside the vacuum, to be checked if they affected TC measurement with the pi. Gauge still sparks in the upper HV cage.

Sunday, December 03, 2023, 22:02 : Vacuum looks good.  4e-7 T.   Heating up target for Monday morning. 1A/30s up to TGHT:580A, TBHT:230A

Monday, December 04, 2023, 12:21: This morning, increased BIAS to 30kV. Ran mass scan with adjusted beam tune up to FC0. This mass scan was repeated with inactive quadrupole elements up to FC0 to compare with Friday.  2023-12-02_RBsalt_SIS_test1.txt and 2023-12-02_RBsalt_SIS_test2.txt

Tuesday, December 05, 2023, 14:12 HV tests restarted, TC wire brought closer to the ground wall. IG1 at 2.3e-6 T. Ramping up HV.

Wednesday, December 06, 2023, 13:48 Both yesterday and today the TC wire was not close enough to spark even at 60kV. Venting the chamber one more time to bring the TC closer. 

Thursday, December 07, 2023, 10:18 Vacuum at 5e-7T we see sparks at about 47kV. Lost control of epics during sparks, PS shut off manually. Everything recovered after.

Thursday, December 07, 2023, 13:32 After spark tests at ~55kV, Pi seems not to be affected by the sparks. Tests without the power surge components yielded similar results. We discovered that the sparks on the TC are partially diverted by spark gaps and probably other elements in the top HV cage.

Friday, January 19, 2024,  15:00: after troubleshooting for quite a while, we fixed the problem by resetting/reconfiguring the canbus controllers. IOC reset did not help the problem and nor did power cycling the box 2A-5, which is believed to be routed to the hall probe.

noted that resetting the IOC did trip the BIAS and drop it to 0V.

Monday, July 29, 2024, 17:35   sparking is too frequent (decided at 24kV) to warrant attempting to condition HV up to 30kV. must determine the cause of this sparking. thus cooling target overnight.  will remove internal wires and reheat.

Tuesday, July 30, 2024, 08:32 after cooling, test stand was vented, wires removed, and subsequently pumped down. 

now beginning TGHT TBHT ramp to 580 230 at 1A/30s

Tuesday, July 30, 2024, 10:02  during TGHT TBHT ramp, HV was slowly increased to 35kV to assess high voltage stability. Throughout, and at 35kV, there were no sparks seen at all.

Tuesday, July 30, 2024, 14:45   at ~24kV, the bias is sparking approximately every 4 minutes. 

Tuesday, July 30, 2024, 17:28  When sparks slowed, bias was increased, but ultimately the sparking behaviour persisted. The bias was then dropped down to 0 and TGHT TBHT cooled at -1A/30s to 0A for target removal tomorrow.

 22:55 Cooldown completed to remove the voltage wires from inside the vacuum box.
