April 22-25

– Four stores provided ~64 hours of luminosity
– Store 8701 set a new record with a initial luminosity of 416.61E30
– Booster RF system trips caused some minor down time
– Pbar debuncher kicker repairs interrupted stacking for three hours
– Beam instability at the beginning of store 8702 caused a loss of luminosity

*The integrated luminosity for the period from 4/25/11 to 5/2/11 was 71.36 inverse picobarns. NuMI took 4.06E18 of beam during this same time period.
