Store from last shift ended 02:37. Voted to end the store at 00:50 when ZDC rates were < 40Hz, i.e. ~1/4 of rate at beginning of the store. The last hour of the store MCR performed crystal collimator studies. Blue quench link interlock during dump. Thereafter recovery leading to MCR being unable to bring on RHIC RF accelerating cavity voltage. They had to call for an expert and are now setting up the machine again. 2. Run 4780 (from last shift) with 303k trigger 1 events. Run 4781 with 79k trigger 1 events. 3. None other than the ones noted in previous shift. ------------------------------------------------------------
