Items addressed from our side inside of the Hall:
 
* Heidi replaced an N2 pressure sensor. Thermal hotspot Camera was checked?
 
* Jerry and others worked on the pump on top of the HMS
 
* Ellen went into the hall to check various cryocomponents.
 
* AC work in the CH completed
 
 
Items addressed from our side of the Hall:
 
* Alex and Hanjie completed the DAQ computer transfer, the DAQ was verified with LED data taking. The 50k replay script works. Alex is confident with a 10% higher current.
 
* Bob worked on the scaler.
 
* Bill Henry worked on repairing the alarm handler. (Starting the DAQ no longer generates the warning on the alarm handler.)
 
* Peter verified the new changes for the hcana, message to Mark: "Please go ahead and commit the changes".

Current Status

Current Run Plan

  • Continue production
  • Half wave plane change at 11 a.m.
  • Moller measurement starting 8:30 a.m., last Friday for the day shift.

Issues

  • Thanks to Bob's effort, the scalar is now displaying in between the runs. This is a significant time-saver especially during the part of the run plan when the PS needs to be changed every 20 minutes. (Thanks Bob)
  • DAQ seems to be able to handle 20% higher right, LD2 runs are currently running at 12 uA (instead of 10 uA from the previous day.)
  • 8pm, DAQ crashed in the middle of the run, Alex was contacted to the restoration. (Near future protocol on DAQ issues, Bob is the on-call for the DAQ issues).

A few new/raised concerns:

1. During the DAQ Coda configuration changes, the instruction is very unclear if a "RESET" procedure is needed. We need to make the wiki instructions clear on this part. Because of this ambiguity, we potentially might have lost 1 good run on this. 2. Part of the run plan requires changing setting, and beam current, frequently, as a result, the run sheets are not completely filled. 3. DAQ crashes during the run-ending process, in this case, the Run End log is not generated. It is not clear how to keep records for such runs
