Minutes of the weekly analysis meetings


6/12/2012: Present: Jixie, Min, Pengjia, Melissa, Jie, Alex, JP, Chao, Toby, Melissa, Ryan, Vince By-Phone:

Feature Presentation:
1) Min: analysis database (run information table)
Beam energy, start time, P0, Theta0 for each run have been written into the table
107 runs are still missing. Chao will take care of these runs.

2) Jie: Finished VDC T0 calibration.

Status Update:

  • Ryan:

1) Updated target_encoder, HWP status, prescale factors in the mysql database. See details here.

  • Pengjia:

1) BPM: obtained noise for every gain setting
2) BCM: Gain is unstable before March 10. Need absolute uncertainty of calibration. Alex will look into it.

  • Toby:

1) Picking out good TE measurements. Match TE points to the right material. Will do new fits.
2) Updated target log book on the wiki.

  • Chao:

1) Improved helicity decoder
2) Will prepare run information table for further analysis

  • Melissa:

1) Working on Cherencov calibration



5/30/2012: Present: Jixie, Min, Pengjia, Melissa, Jie, Xiaochao, JP, Chao, Toby, Melissa By-Phone: Karl, Guy

General discussion (JP, Karl, ...):
1) Chiral Dynamics Workshop will be held at Jlab in Aug 6-10. The deadline for submission is June 1.
Please submit abstract.
2) Gorden conference will take place at the same time. Submit abstract before deadline!
3) G2P group will give 3 talks for the Hall-A collaboration meeting .
We will meet next Wednesday 13:00-15:00 to practice the talks and giving feed-back.
Jixie has reserved L207. (Jun 6, 13:00 - 15:00).
4) Karl will provide plot|slice material to Bob and Jixie for their talks in Hall A collaboration meeting.

Feature presentation:
1) Pengjia: Preliminary BCM calibration Result

Status Update:

  • Guy:

1) Have analysis meetings in Israel. Analyzing the data.
2) Need to discuss how to do the dilution factor calculation.

  • Jixie:

1) working on optics analysis.

  • Min:

1) Calculating the uncertainty of pointing. Discussing with Nilanga about it.

  • Chao:

1) Working on helicity reconstruction. Need Pengjia to cross check this when finish.
2) will cross check BCM calibration soon.

  • Toby:

1) Preparing the target material TE table for target calibration.

  • Jie:

1) Working on VDC T0 calibration. Need more statistics to get the result.

  • Melissa:

1) Working on CC calibration.
