Revision as of 15:56, 3 May 2011
General Information
This is the spot for all things moller polarimetry. Information on how to take moller measurements, spin dance and polarimetry results, and system specs will eventually be put here. This page is currently under construction, and will be updated frequently in the upcoming weeks.
Preliminary results
Measurements for 2011
Data points can be found in /group/qweak/gaskelld/kumac/qweak_by_day_2011.dat
Last updated April 29, 2011
Measurements for 2010
Note: Measurement on "Day 39" low due to likely hardware issue.
Moller info for Qweak
- The Qweak Moller "how to" is officially up and ready for viewing. (version 1, updated jan. 26, 2011): Qweak Moller "How-To"
- The following is a plot showing good tune of the apparatus. It was taken from run 700, hallc:p ~ 1159 MeV, with a 1um target. (Jan. 30, 2011)
Moller measurement summaries
This will be a sort of "Cliff Notes"section, that will summarize each test and link to the hclog and elog entries.
May 2, 2011 Measurement had low rates (~11kHz), and collimators IOC died and needed re-booting. hclog
Apr. 29, 2011 Measurement included a spot change. hclog
Apr. 27, 2011 Normal measurement, a few beam trips. Leakage check. hclog
Apr. 25, 2011 Hall A boiling studies. Many missed helicity gates. hclog elog
Apr. 22, 2011 Beam position on target moved after IWHP to OUT changed. Most of that IHWP setting is suspect. hclog elog
Apr. 15, 2011 Slit studies and regular measurement. hc-log summary hc-log plots e-log summary
Apr. 13, 2011 Slit studies and regular measurement. The quad tuning was painful - mcc re-cycled the quads 3-4x. hclog-results hclog-slit test e-log summary
Apr. 11, 2011 Regular measurement - polarization increased from the 11th, but not quite noraml. (~86%) hclog e-log summary
Apr. 8, 2011 Changed MPS to 100us. Polarization abnormally low. (~85%) The MPS change appeared to not be the cause. hclog elog
Apr. 6, 2011 Regular measurement. Measurement 1% better than from same spot on the 4th. hclog elog
Apr. 4, 2011 Shifted beam left by 0.5mm to see effect of polarization. hclog elog
Mar. 31, 2011 Study of charge asymmetry on polarization. Used "old" method of just changing the PITA voltages. Some difference, but inconclusive. hclog elog
Mar. 18, 2011 Study of charge asymmetry effect on polarization. hclog elog
Feb. 24, 2011 Regular measurement. Noticed bug in "calc_bpol_byquartet". hclog elog
Feb. 22, 2011 Final run disrupted by cryo events. hclog elog
Feb. 19, 2011 Results outside of statistical error. Tune and rates a little odd at first. After cycling Q3 again, rate=17 kHz/uA. hclog
Feb. 10, 2011 Spin dance. Position of 3c12 visibly wandered. hclog summary hclog pol. measurement elog
Feb. 8, 2011 Measurement of vertical polarization (spin rotator off) ~-0.60. hclog
Feb. 7, 2011 Checked HV - looked good, and then measurement. Several beam trips. hclog elog
Feb. 4, 2011 Measurement, good beam. hclog summary (no plots) elog (with plots)
Jan. 30, 2011 Checked HV, rates, and re-did a collimator scan. hclog hclog plots elog (also with plots) collimator scan (with spreadsheet)
Jan. 21, 2011 Straightforward measurement. Good backgrounds. hclog
Dec. 14, 2010 Background studies. Tweaked HV, looked at collimator 5. hclog
Dec. 10,2010 Verified timing for the main coincidences and accidentals. hclog
Dec. 9, 2010 Scaler coincidence and accidental measurements elog
Dec. 6, 2010
- Rate and current dependence studies. hclog elog
- Quad tune test. hclog summary
- Rate and current dependence studies. hclog elog
Dec. 4, 2010 Moller solenoid field scan for foil misalignment. Solenoid field at 3.75 self inconsistent. hclog elog
Nov. 23, 2010 Spin dance. hclog summary elog (duplicate)
Nov. 14, 2010 Commissioning! Gain matched calorimeters and scintillator HV. Optimized quad tunes, some collimator studies, and made some measurements. hclog
Also: an hclog note on moller backgrounds sensitive to beam position near raster. (Dec. 4, 2010)
Table of good Moller runs
The following are runs made from straightforward moller measurement runs, not spin dances. Note, missing data can/will be added over time. The Nov. 14, 2010 commissioning run is NOT included. (we were messing with camac pre-scales, et cetera.)
