    Comments: 8:38 Beam down: arc power supply tripped twice MCC called a specialist. During the beam down: - NMR measurement without laser - NMR measurement with laser --> taget polarization 31 % - Pedestal run 9:46 beam back 10:53 last run in |_ configuration, E=3.4 GeV, Ep=2.199 GeV, theta=15 degree Tot # of events 17.6 M beam secured during momentum changed 11:27 beam restored. Begin // runs @ E=3.4 GeV, Ep=2.030 GeV, 15.5 degree 11:45 Beam down (PSS fault in the injector) 12:55 beam back (PSS problem not fixed but the need beam to troubleshoot it) 14:00 coda crashed 14:55 coda back.
