keyword=Moller resultsMoller results on November 17 10:35 - 19:00
- Crew: O.Glamazdin, A.Sasha, FADC team
- Wien filter angle is 74.73°
- The raster was ON. The half wave plate was IN.
- 13:17 - We've lost control on the Moller target.
- 16:30 - After a lot of reboots of IOCHLA the Moller target is back under control.
- 17:32 - MOLLER IS ALIVE! Start taking data.
- Beam current was 1uAmp to use ARC2 energy lock. Due to that the beam polarization was measured with targets 4 and 5 only.
- Moller results have to be corrected on the beam energy fluctuation.
