Overview

This page gives instructions for various aspects of the experiment relating to each of the major subsystems and shift tasks.

Shift Roles

  • Shift Leader: Executes the Run Plan according to the Run Coordinator's instructions
  • Target Operator: Monitors the target system
  • Data Quality Monitor: Starts and stops CODA DAQ runs and monitors the quality of the data that is being recorded

Reporting and Logging

All shift takers should regularly log shift details in HALOG - the Hall A electronic logbook.

Shift leaders should fill out Beam Time Accounting (BTA) information during the shift.

Taking Data

  • Using the CODA DAQ
    • GUI Description
    • Starting a Run
    • Stopping a Run
  • Monitoring the data
  • Online analysis
  • Shift checklist

online analysis

This section contains instructions for running the replay script with all detectors on a-onl@aonlX.

  • Login to a-onl@aonlX (X=1, 2, 3, 4)
  • once logged in, type gosbs => this takes you to the directory where the analysis should be done, and sets up the correct environment variables.
  • open the analyzer by typing analyzer
  • once in the analyzer type .L replay_gmn.C
  • for routine analysis type replay_gmn(runnum, nevents), with:
    • runnum the run number you want to analyze;
    • nevents the number of events you want to analyze.
  • for expert analysis only type replay_gmn(runnum, nevents, firstevent, file_prefix, firstsplit, nsplits, pedestalmode) with:
    • firstevent the event number from which you want to start the analysis;
    • file_prefix the prefix of the file you want to analyze;
    • firstsplit the split/segment number at which you want to start the analysis;
    • nsplits the number of splits/segments you want to analyze
