SSRL operates at 500mA and employs a frequent fill schedule to maintain the SPEAR3 current approximately constant. Automatic injections will be conducted every 5 minutes. Automatic injections will only occur at the designated 5 minute intervals (i.e., on the hour and every 5 minutes thereafter). If the injector is not functional at the designated fill time, then the fill will be skipped. The current will be replenished at the next scheduled fill time after the injector is repaired and normal injection intervals will resume. The operator will give an audible announcement prior to first injection if the current has decreased more than 10%.
Beam time shifts with the "low alpha" operating mode are scheduled for 11/23/12 (1200)-11/26/12 (0600), 2/8/12 (0600)-2/11/13 (0600), 4/19/13 (0600) -4/22/13 (0600) and 6/14/13 (0600)-6/17/13 (0600). During these low alpha shifts, SSRL will operate with reduced current in the 100 mA range and top off will be less frequent depending on user requirements, anticipated every 20 minutes rather than every 5 minutes.
