Overview:

The plan is to take SHMS singles with Hydrogen and Aluminum targets. Please set the HMS/SHMS angle 
and momentum settings accordingly. See Kinematics Sheet.

Pre-Analysis

1. Start a Run. We will be taking roughly 1-hour long runs, for which you'll need to keep an eye on the time.

3. In the middle of the run, once enough statistics have been accumulated, execute the 50k event replay scripts for each spectrometer to monitor the detectors. In case you are not already in the online analysis directory, from a cedar machine, do the following:

  Login to cdaql1 machine and go to hallc_replay directory:
  > ssh cdaql1 
  > go_analysis 
  for SHMS detector check: ./run_coin_shms.sh <run_number>
  for HMS detector check: ./run_coin_hms.sh <run_number>



3. After full run, check the Good events and Update the file on Google docs

a. Login to cdaql1 machine
b. Update the file " standard.Kinematics " : usually opened in HIGH VOLTAGE Monitor (HCDESK 2 )

  path :

c. Analyze the run with :
