keyword=Target polarization summary
Summary of target polarization for the cell Armagedon (currently in use):
Average of the two calibration numbers are used (2.65%/mv)
When there is no beam, the highest polarization- peak=16 mv, pol=42%; typical polarization- peak=15-16 mv, pol=39-42%.
With 14uA beam on target:
Longitudinal- peak=12.4-13.1 mv, pol=33-35%. (lasers always on).
Transverse (laser off): peak=10.5-11.5 mv, pol=28-30%; (Temp effect)
(laser on): peak=11.6-12.2 mv, pol=31-32%.
