Current push to 70, BLA cal

Log Number: 4513185Logbook(s): Entry Makers: samariBody: 

We had to derate 4 cavities (2L05-1, 2L03-1, 1L07-8, 1L22-6) . All small amounts except for 1L22-6, which had to be taken down 2 MV/m due to KRRP.
at 68 uA, our instantaneous loss was near constant at around .51, which gave us problems. After verifying very clean beam on BLMs, we performed a BLA cal from 0L02 to 0R08 and onward. unfortunately, the instantaneous loss is hovering slightly negative, indicating the BLA cal overshot.
