Procedures

Hall A call-in instructions:

  • Call RC first.
  • Techs on site 7am-4:30pm Mon-Thu, 7-11am Fri. RC will call Hall A work coordinator (Zak) during normal working hours. After hours, RC calls Tech on-call.
  • After 9pm everything non-emergency needs to be deferred. What is emergency and what's not? Call RC. RC talks with Mark to decide.

Hall Access procedure:

  • Access check list (binder on the counting room desk) needs to be filled out before making *any* access.
  • Scan (take pictures with phone) and post it to the logbook.
  • Any work inside the SBS, BB boundary need to have PS locked out -- requires two QEWs to throw the big switch. Exception: field measurements.

Status Update

Overall Summary

General

  • We are optimizing the target while awaiting beam.
    • If there is no other work in the hall tomorrow, it'd be a good time to turn on magnets for the target.
  • Work on the GEMs is ongoing.

Shift Plan

  • All shifts are canceled through Wednesday Day shift.
  • Starting Wednesday Swing, shifters are on standby.

Beam

  • None!

Hall A Dump Repair

  • Corrosion due to standing water is not a concern.
  • Still need to dry out water and apply decon gel (hopefully started today)
  • Need to restart pump
  • All information for Stuart has been collected and deployed. Still need his approval?
  • "Hope is that they will get the floor dry and the de-contamination gel on today. Let it dry overnight and then Carroll et al. can get in the room tomorrow. There is still electrical checks to do, but if they can get in and no issues are found, hopefully they can get the flow of water restored." - Doug
