Analysis How-to

New analyzer (Pol He3 Run Group, 2020)

Instructions for the Online Monitoring for Pol He3 Experiments

Short Analysis Instructions

• Connect to online analysis machine:

 $ ssh cdaq@cdaql1

• Source environment and go to analysis folder:

 $ go_analysis

The standard.kinematics files should be automatically updated for the Pol He3 Run period.

• Check if the kinematics for the run are up to date

There should be a window opened with the standard kinematics for each run, if NOT, then:

 $ emacs DBASE/HMS/STD/standard.kinematics &
 $ emacs DBASE/SHMS/STD/standard.kinematics &

If the kinematics for the current run are NOT updated, please update.

• Run online analysis after 50k events have been collected
• Run online analysis:
  • onlineGUI will pop-up automatically
  • <runNum> : run number; If it is omitted, the system will analyze the most recent (or current) run.

 $ ./run_hms.sh <runNum>
 $ ./run_shms.sh <runNum>

• Run full online analysis after the run has been completed
• Run full analysis:
  • A `pdf` and `root` file will be saved under `HISTOGRAMS`
  • <runNum> : run number; will analyze last run if omitted

 $ ./full_hms.sh <runNum>
 $ ./full_shms.sh <runNum>

Detailed Analysis Instructions

• Connect to the online analysis machine:

 $ ssh cdaq@cdaql1

• Source environment and go to analysis folder:

 $ cd hallc-online/hcana
 $ source setup.csh
 $ cd ../hallc_replay
 $ source setup.csh

• Run HMS analysis:
  • -q : exit analyzer after running
  • <runNum> : run number
  • <numEvents> : number of events to analyze; 50000 for short, -1 for full replay

 $ ./hcana -q "SCRIPTS/HMS/PRODUCTION/replay_production_hms.C(<runNum>, <numEvents>)"

• Run SHMS analysis:
  • -q : exit analyzer after running
  • <runNum> : run number
  • <numEvents> : number of events to analyze; 50000 for short, -1 for full replay

 $ ./hcana -q "SCRIPTS/SHMS/PRODUCTION/replay_production_shms.C(<runNum>, <numEvents>)"

• Open HMS onlineGUI:
  • need to run HMS analysis for 50000 events before this
  • -f : which config file to load
  • -r : which run to display
  • <runNum> : run number

 $ cd onlineGUI
 $ ./online -f CONFIG/HMS/PRODUCTION/hms_production.cfg -r <runNum>
 $ cd ..

• Open SHMS onlineGUI:
  • need to run SHMS analysis for 50000 events before this
  • -f : which config file to load
  • -r : which run to display
  • <runNum> : run number

 $ cd onlineGUI
 $ ./online -f CONFIG/SHMS/PRODUCTION/shms_production.cfg -r <runNum>
 $ cd ..
