HV_logger_SBS repository contains the tools needed for the EPICS logging of HV information for all the detector sub-systems used in Jefferson Lab Hall A Super BigBite Collaboration (SBS) experiments. The entire EPICS logging machinery for SBS experiments can be found at /adaqfs/home/sbs-onl/logentry_scripts/.

1. How-to:

1. Every time when there is a change in HV mapping for any sub-system, do:

   ./get_dictionary_and_siglist.sh <name_of_sub-system>

2. Check the Dictionary and Siglist directories to make sure the updated .dictionary and .siglist files are in place for all the sub-systems.

3. Then to get the .results files for EPICS logging, do:

   ./HV_logging.sh <name_of_sub-system>

2. List of sub-systems:

• BB_HV : This includes HV channel info for BB Spectrometer (i.e. BBCal, BBHodo, BBGEM, GRINCH).
• SBS_HV : This includes HV channel info for SBS Spectrometer (i.e. HCal, et cetera).
• LHRS_HV : This includes HV channel info for LHRS.

3. Example execution:

To log HVs for BigBite spectrometer (BB_HV), one needs to do the following:

./get_dictionary_and_siglist.sh BB_HV

Check to make sure updated BB_HV.dictionary & BB_HV.siglist files exist. Then do,

./HV_logging.sh BB_HV

Now, a BB_HV.results file should be generated inside Results directory.

4. List of scripts:

1. setup.sh : Sets proper environment to parse most up-to-date files.
2. Dictionary/make_HV_dict.pl : Creats a .dictionary file using .hvc file for all sub-systems.
3. Siglist/hv_dict_parse.pl : Generates .siglist file with epics variables using .dictionary file for all sub-systems.
4. get_dictionary_ana_siglist.sh : Executes the scripts mentioned above in proper order.
5. HV_logging.sh : Generates .results files with caget information using .siglist and .dictionary files for EPICS logging for all sub-systems.
