21:15 We're ready, accelerator tries to deliver beam
21:25 A-line bcm problems. Time estimate = 40 minutes
22:20 beam about to be delivered, right dipole too high (2.622 vs 2.617 GeV/c)
22:26 oops. beam off
22:29 beam back
23:00 beam intermittent
23:20 change the momentum setting in the right arm from 2.617 to 2.629 (to match the right dipole) and hope we can make up for it in software.
23:50 try to lower P0 right back to 2.617. Dipole does not change. Calculate desired dipole current (927.58 A) and try putting in that value.
