The main objective of week 9 RC duty was to focus on the production of the data and also complete some of the very important studies such as TAC run. So In addition to production, we completed some special tasks as well. We had 163.0h of scheduled hours while CW beam on target was 97.0h(60%) and ABU was 87.4hr(54%). We lost total 10.2 hours on various sectors such as radiator change, TAGH HV alarms, Vacuum pump alarms, resolving DAQ issues and stoping/starting runs as well as FCAL base resets. Production was mostly smooth when beam was available. Over the weekend, we continued production. On Sunday, day and swing shift was used for TAC run. We collected 8 hrs of data for the TAC run using CCAL as TAC when hallC was running at 45.0 ua. Results obtained from TAC run study was pretty good. We produced good amount of data till this morning(March 15). On march 8th, we finished another round of high intensity test at 900 nA by using different absorbers such as W,Pb,Sn and Mo. Approximately billion events were collected for this study. Some of the outstanding issues that came during the week and were resolved as quickly as we can were the following.

  • DAQ issue (live time drops to 0%): recovered by recycling gluon01 crate. While on the another DAQ issue, rocDIRC ioc needed to be rebooted.
  • Vacuum Pump alarm: Turbo pump power was power cycled. Possible power glitch.

TAGH HV alarm issue(issue appeared in the past as well). This time all channels alarmed. After power cycling the crates issue was resolved.

  • HallD beam stopper mismatch. MCC could not put us in beam permit until this was resolved. Took ~12 hours to get resolved. Problem was that network switch did not communicate and had to swap with new one.
  • Number of FCAL bases were locked up and all of them were reset after the run ended successfully and before starting another new run.

Important tasks planned for the remainder of run period:

  • Final round of high intensity test scan at 900 nA with different trigger thresholds.
  • Straight-track run with Drift chamber magnetic field off at ~50nA.

Overall week was pretty good but still we are significantly behind and 5 days left are not enough to reach to targeted statistical goal. We need to perform better on next GlueX-II run.
