For the E2 run, it is planned to have four persons always present: the Operator, the Expert, and two "Trainees". The operator will carry out routine tasks (e.g., lock the pre-stabilized laser, the mode cleaner, a single arm, etc.) using well defined procedures. More complex tasks, such as alignment, locking a multi-cavity interferometer, or calibration, may not be so well prescribed. The official expert on shift (and perhaps other experts on call) may well be needed for these tasks. Trainees, as suggested by their title, should try to acquire expertise (including general understanding of IFO behavior) from the Expert and other experienced scientists on hand. Ideally, trainees should ultimately become expert enough to lead scientific monitoring shifts in future engineering runs and, of course, in the science run.
 

• Check the interferometer state at the beginning of each shift, following a checklist :
  (e.g., verify PSL gains are correct, check positions of optical levers, etc.)
• Take standard set of spectra at beginning and middle of shift
  (e.g., feedback from mode cleaner to PSL, laser intensity noise, etc.)
  for comparison with reference spectra, with discrepancies noted.
• Follow up worrisome discrepancies (e.g., sudden appearance of spectral peak) with investigation
• Periodically check output of Data Monitor Tool processes running in background. Look for any worrisome systematic changes (e.g., gross non-stationarity).
• Periodically check trend data on key interferometer channels for gross changes.
• Investigate "non-trivial" EPICS alarms, including those produced by DMT processes.
• In general, make sure that electronic log is kept up to date.
• At the end of shift, report to newly arrived shift crew on the inteferometer state and any known anomalies.
• Fill out questionaire on utility of available (and unavailable!) software tools used on shift. If appropriate, contact software writers directly with suggestions for improvement.
