Comments: 00:25 Target alarm due to temperature fluctuation; trying to slowly bring beam back 01:25 Target is responding well to slow ramping up of beam -- currently at 100 uA 01:45 Target has PID issues at 100 uA. Target alarm goes off. We've decided to run at 90 uA beam for production (see HALOG 298690,298691) 02:30 Multiple beam trips causing target alarm for past 20 mins. 04:00 Production at I ~ 90 uA running smoothly 06:46 Smooth data taking all night, up until LHRS coda crash -- no response from TS. (See HALOG 298727.) 08:00 RHRS Q2 Liquid He level is low; calling tech-on-call to help fix the problem.
