keyword=Missing carbon hole with current beam positionWe totally miss the carbon hole at current BPM position. As stated in last log, MCC could not adjust our BPM X position to requested value, unless they take some longer time and try hard to get it through compton.
Current BPM are BPMA = (0.3,1.3) BPMB = (1.4,1.5). As seen on 2nd plot, the X position is so off that beam bumped into its support structure in horizontal dimention.
