Comments: 16:30 access to reset right arm magnet controls 16:45 rebooted the magnet control ioc of the right arm 16:46 right arm septum tripped 17:00 Brian fixed the sync problem in the right arm 17:30 both dipoles have tripped 19:45 no hope to fix right dipole today - take data with one arm. end of access. 20:45 injector problem no beam yet 21:15 beam back 5 muA 21:20 beam at 20 muA 21:25 beam at 40 muA 21:35 requested 60 muA 21:50 MCC called because they cannot do better than 40 muA because of trip in the ion chamber in the left dump 22:10 after David's intervention they raise the trip limit and got us to 60 muA 22:30 adjust detector HV to accouont for these conditions. 5655 - production run with 1 arm 60 muA. 23:00 we will turn the right septum on. ask for beam off and wait that the temperature of the coil goes below the limit of 7.53K. 23:10 start ramping up the current in the R septum to 316.92 and set the L septum at 323.61 23:45 beam back 5656 - production run with 1 arm 58 muA
