Friday, August 02, 2024, 16:33  data at test number = 7462 can be further visualized using the shared jupyter notebook code.  data taken at anode voltage 260V was disrupted due to a spark derailing a number of optics elements in the beamline. they were soon corrected, but this data was missed.

 Friday, August 02, 2024, 16:34   -   mass scan with  180V 70A      (Argon ON) ---- doesn't seem to be recording background noise well. ie the common background recording artifact is present. records constant numbers instead of numbers in range (1e-13,5e-12). often appears in mass scan image at slants

Wednesday, September 11, 2024, 14:49 Mass scan recorded.   2024-09-11 HPTiC-24D - scan 1.txt ... FC6 problem with recording background level data persists

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.
