After the scan finished I found the Test Stand EPICS screens whited-out. Decided with Friedhelm to leave it as it was for the night and to contact Controls next day to reboot it without tripping the heaters and the HV.

April 3, 2014:

Found everything recovered. Except: “SOURCES ARCH IS RUNNING” was red. So, I restarted it. Jane Richards and Friedhelm didn’t do any IOC reboot. Also found that the data from yesterday’s scan was saved (see the previous scan).

Did another mass scan:  plotdump-local-clean.txt_Apr3_14_10-18-13.txt

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, 13:50   target at 580 230. increasing bias. 

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. 

Tuesday, September 10, 2024, 16:21:   Target installed in test stand by Brady

Tuesday, September 10, 2024, 20:27   Pressure at 4.9e-6, increasing TGHT TBHT to 580A/230A at 1A/30s

Wednesday, September 11, 2024, 10:00 The TGHT TBHT parameters were mistakenly reversed during heating. TBHT was dropped to 230A and TGHT increased to 580A at 1A/30s.

Wednesday, September 11, 2024, 13:50 TGHT TBHT at 580 230.  Increasing BIAS/EE/EZL to 30/2.5/13 kV.

Wednesday, September 11, 2024, 15:53  increasing BIAS and EZL to condition high voltage 

Wednesday, September 11, 2024, 16:32 at 37kV (EZL 22kV), TGHT timed out and cut the current to the target. I elected to leave it cold rather than suddenly reheating it, and am cooling down TBHT at -1A/30s, while continuing to increase BIAS for conditioning.

there have been no sparks at all and I'm unsure of what precipitated this event. None of the 'trip indicators' on the TGHT panel lit up during this event. I will bring this up with Keiko/Roberto tomorrow Sept 12.

Wednesday, September 11, 2024, 17:06  one spark occurred at 49kV

 Wednesday, September 11, 2024, 17:15  now at 50kV, EZL at 33kV.  Over 30 minutes there was just one spark at the HV bias.
