    Comments: 8:10 ended with point @ E=3.4 GeV, Ep=3.o28 GeV, theta=15.5, |_ tot # of events for this configuration: 109.0 M come back to \\ configuration. NMR (with lasers) 31 %, NMR (without lasers) 33 % Change the momentum setting. Problems with hadron arm 8:45 ask for beam back (RMN for target done) but MCC have to recycle a dipole 8:54, beam back begin @ E=3.4 GeV, Ep=2.796, \\ configuration run only on electron arm 9:12 hadron arm ready--> run on two arms 9:39 ask MCC for a Bscope but cannot do it at appropriate frequency (see note on Hall A Elogbook entry 3703 and Acc Elogbook entry 56149) 14.15 end // runs @ E=3.4 GeV, Ep=2.796 theta=15.5 28.5 M events 14:30 NMR. Target polarisation: 33 % 14:33 logout-login adaqs2 to fix the Elogbook problems. 14:40 start |_ runs @ E=3.4 GeV, Ep=2.796 theta=15.5 15:35 coda crashed
