Entry number 133187

• Stable Production running ("Pion" mode) over most of Sunday Swing and Monday Owl shifts (uptime ~ 76 %).
• Sunday Swing shift started with no beam in the accelerator due to a Gun 2 HV trip and injector vacuum problems. Initially, MCC was concerned that the Gun 2 wafer may have been damaged, but the problem turned out to be related to a faulty cable (Gun 3 vacuum) coupled with an inopportune IOC reboot (which reset the Gun 2 steering lens Y-stage). After isolating and correcting the various faults, MCC was able to deliver beam into Hall-C at ~ 18:30.
• Several Production runs with the latches/matrices set back to "Randoms" mode were taken at the end of Monday Owl shift.
  

• Target is LD2
• IHWP is OUT
  
• Beam Current: 35 uA
  
• Beam Quality: Good. Stable. Halo 3/4 at 18/20 Hz/uA.
  
• Integrated Coulomb Counts (including "Effective" Coulombs): 51.9 C (IN: 24.5 C, OUT: 27.4 C)
• Coulomb Counts for Pion Running:  5.0 C (IN: 2.9 C, OUT: 2.1 C)
  

• Moller and Mini-spin Dance on Monday, Feb.12 (Day and Swing shift).
• "Transverse" production data following Mini-spin Dance (likely part way into Monday Swing shift).
• Feb.13, Day Shift: Special DOE tour.
  
• Resume "Transverse" production data running after MCC recovers from the special tour.
• Special Randoms measurement tentatively scheduled for Wednesday, Feb.14.
  

• See updated "Calendar" attachment at the end of Saturday's RC report.
• SMS reverse polarity studies tentatively scheduled for Tuesday, Feb.20.
  

• Greg Smith will be away from Feb.6 until Feb.13; During this time, the "Target On-Call" person will be Mike Seely (pager 584-5036).
  
• Alex Coppens will be the "DAQ On-Call" person for the next few weeks (pager 584-5493).
• Transverse running:  Paul King has provided a draft runplan (see elog 133006).
• Special Randoms Measurement: Herbert Breuer has provided a draft runplan (see elog 133044).
• Items for Shift Crew: 
• good_for_GUI.pl :  The "comment" field now needs to be completed when cataloging "Pion mode" Production Data runs (see elog 132986 ).
  
• Hall-A charge feedback: If Hall-A is taking beam, we should turn on the charge feedback for Hall-A. The Hall-A IA feedback GUI looks similar to the G0 beamfeedback GUI and is presently located in a separate workspace on the same console. (IF the "slopes" have not yet been calibrated and entered into the IA Calibration Constant  field on the Hall-A IA feedback GUI, please follow the procedure outlined in elog 132913).
• SMS Reverse Polarity Tests: We need to firm up this up in our schedule.
  
• SMS field scans, if needed, should be worked into the schedule to perhaps coincide with (e.g. bracket) the Reverse polarity studies.
