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.
