Overview

This How-To discusses the necessary steps required in order to take a pedestal run utilizing the single arm DAQ's. Furthermore, the steps required in-order to determine the appropriate FADC thresholds are discussed.

Taking Pedestal Runs

  • Ensure that both single arm DAQ's are configured with the "fadcnothr" flag, which is activated via. of the pre-scale GUI, and the configuration has been saved
  • With both arms take at least 1000 cosmic or EDTM triggers and note the run numbers

Determining the FADC thresholds

  • With the pedestal runs complete, open a terminal and SSH into cdaql1
ssh cdaq@cdaql1
  • Setup the hallc-online analyzer
go_analysis
  • Descend into the hallc-online hcana/podd directory
cd ../hcana/podd/hana_decode/
