This is the plan for running high intensity tests for the Spring 2017 run
Run Conditions
- Radiator: JD70-100 (58 μm - 4.8·10-4 R.L., 7×7 mm²) and/or 3x10^-4 Al radiator
- CW beam current up to 500 nA
- Tagger quadrupole on (-4.2 A).
- 5.0 mm collimator hole
- Detector Settings
- CDC: 2125V HV, with following trip settings:
- 24 uA for 300 nA beam
- 36 uA for 500 nA beam
- FDC and TOF are fine with nominal settings
- Lower TAGH counters remain off
- CDC: 2125V HV, with following trip settings:
- Trigger settings
- Standard triggers
- Include BCAL+FCAL+ST?
- Prescale factor: 3?
- Standard triggers
Run Plan
- 2 current points: 300 nA and 500 nA
- present data at 150 nA used as reference
- 2? runs: 1 PARA, 1 PERP
Analysis Plan
- Study rho, omega rate
- Statistical precision of asymmetry
- 1 run will give rho asymmetry on level of 40 +- 1 %
- omega statistics are factor of ~10 less
- Estimate fraction of accidentals?
