    keyword=beam position

    our beam position tolerance on BPMs A & B are 0.0 +/- 0.1 mm. at 10 microA, the positions were 0.0x0.0 mm on BPMB, but 0.2x0.5 mm on BPMA. MCC claims that at this high current, they do not have enough correctors to fix both BPMs. so i makez a command decision and ask for the beam current to be 5 microA. now the beam positions are much better, all are 0.0+/-0.1 expect for BPMA in the X (horizontal) which is 0.0 +/- 0.2 mm.
