This page contains offsite online monitoring procedures for Spring 2020.

Procedures

  • An email is sent out twice per day, at 5 AM and 5 PM, JLab time
  • Monitors should create a log entry that includes the run range of plots you examined and any discrepancies that you noted.
    • Please focus on the discrepancies in your log entry, for example a short statement that "Everything looks OK, except the following:" is preferred.
    • If discrepancies exist, please notify the run coordinator with your log post. Current run coordinator: X
    • Monitors are welcome to check monitoring results more often, but are only expected to check the monitoring results when they receive the monitoring email, i.e., once per shift.

Occupancy Reference Plots

CDC Occupancy: There should be a uniform decrease in intensity from the center of the detector outward. Random white cells scattered throughout occur when not enough data were collected, eg empty target runs, trigger tests or no beam. Several contiguous white, dark blue or bright yellow cells which don't match the neighboring cells are a problem.
