- Crew: O.Glamazdin, B. Sawatzky
- Wien filter angle is 17.20°
- The raster was OFF. The half wave plate was IN.
- Beam tuning took 1hour.
- B.Sawatzky and O.Glamazdin: controlled access to the hall A to turn Helmholtz coils power supply on.
- After 100uAmp beam running with Moller dipole turned on moller detector signals looks good.
- Hall A laser phase study was done. Results will be presented after analysis.
