Taking data with polarized hydrogen in single state and flipping helicity once per fill at longitudinal holding field.

Good runs 2230-2239 2244-2249.

Attached asymmetry plot for all runs with longitudinal field,

flip helicity once per run
2201-2206 2208-2210 2212 2215-2216 2218-2221 2223-2224 2226-2227
flip helicity every fill
2230-2239 2244-2245.

Had to restart Compton from time to time, got some tripoffs of WCL6 (but kept it at 3800V.) At the end of the shift we had some HV problems (lost communication with IOC and further tripoffs related to this, with Dtunnel access.

WCL21 did not hold the voltage, lowered it to 3700V.
