Specific Fall Run 2021 Items

• High Voltage Mapping. This is a pdf of the excel spreadsheet passed to epics. Contact Ralph Marinaro, Steve Wood or Rachel Montgomery for the actual spreadsheet. [[1]]

How to Documents

• High voltage and low voltage set up and operation for hodoscope in TEDf with cosmics, including EPICS instructions [[2]]

Software

• SBSTimingHodoscope class which is under continuous development can be cloned from : https://github.com/rachel-m/SBS-offline.git on the branch BB_TH_dev
• Analysis and calibration macros, which are also under continuous development, can be found on the main branch at: https://github.com/rachel-m/HodoSW
• Document about SBS-offline for the hodoscope. The pdf and .docx files are also found on the github. If you add anything relevent to the TH class in SBS-offline please update the docx and pdf files, here and on the git hub.
• Document about the calibration scripts. The pdf and .docx files are also found on the github. If you add anything to the calibration macros please update the docx and pdf files on this page and the git hub.
• Document about the online display for shift workers. The pdf and .docx files are also found on the github. If you add anything to the online display and shift worker code please update the docx and pdf files on this page and the git hub.

Outdated/Preliminary Mapping Below (Just stored here for reference, do not use as of Jan 2021 onwards)

• Cosmics high voltage and low voltage mapping overview (R. Montgomery, February 2020) [[25]]
• Cosmics mapping spreadsheet document, take note there are 3 tabs in the spreadsheet. This mapping misses only signal cables from frame to weldment (R. Montgomery, Feb 2020). [[26]]
