Beam Polarization: Raw Results 2007

6 September 2007 15:10-17:30. E.Chudakov

Bulk cathode.
The beam energy is 1076MeV(accel), 510MeV(linac), 57.375MeV(injector). Injector angle is 36.703^o, the 1/2 wave plate was OUT.
Injector laser attenuation=140, Slit=16.4. Fast raster was ON.

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.
