Setting new NPS Calorimeter HV values

As the cdaq user on any of the cdaql# machines (e.g cdaq@cdaql3) there is a directory /home/cdaq/calorimeter/HV that contains several python scripts and text files containing old HV settings.

• To save the current HV values into a text file run "python3 hv-save-quick.py" The output file is "hv-setting-date-time.txt"
• To save all the current HV PVs (HV, current, trip points etc) run "python3 hv-save.py" . This might take several minutes to complete.
• To change any high voltage PVs from a file run "python3 load-hv-settings.py" you will be prompted for the input filename
  • There is a "production-HV.txt" and "cosmics-HV.txt" files that contain the updated values for both run conditions. Just run the load-hv-settings.py above
  • The format of the file that this script reads must be rows of "PVname = PVvalue" (e.g. "hchv30:00:000:V0Set = 750.0")
    • This is the same format that is automatically generated from hv-save.py. So you can easily reload previous saved settings without any re-formatting.
  • If you dont know the PVnames or you just have HV values in a text file formatted into 3 tab separated columns: col# | row# | HVvalue , then run "python3 formatHV.py"
    • you will be prompted for the input filename. Then run "python3 load-hv-settings.py" with the newly formatted input file generated.
    • Note: the formatHV.py script was only made to reformat Malek's HV file. It ```only formats files if they contain HV values for ALL the channels and are listed by descending column#

 For example:

• 0 0 790.000
• 1 0 820.000
• 2 0 765.000
• ..

• 29 35 790.000
