AGS/Booster Status March 11, 2014 Time Meeting Haixin Huang

2 Status l AGS and Booster are running well to provide beam for RHIC. l Siemens status: No quick fix in sight. Repair the cooling fan for Westinghouse today. Prepare to run AGS with it for a longer time. l AGS vacuum valve incident last maintenance day is under review. l New AGS BLM logic has been tested and put into use today. l H10 noise problem greatly reduced after Yugang found a loose capacitor in the old control board last Tuesday. Only two cases since then, instead of a few for each RHIC fill. l Booster injection field drift still happens from time to time but AGS injection seems stable for some time now. l H section unusual bad vacuum (correlated with drool loss at flattop): vacuum group will check leak to see if pump replacement is needed.
