Beam Polarization: Raw Results 2005

16 June 2005 03:26-6:45. E.Chudakov, R.Pomatsalyuk

New Moeller target test
The beam energy is 3661MeV(accel) 450MeV(linac). Injector angle is -35.001^o, the 1/2 wave plate was OUT.
Injector laser attenuation=73, Slit=18.5. Fast raster was OFF.

The theta acceptance is about +/-15^o? and the mean analysing power is 0.76. The target angle is 20^o. The error is statistical only.
