    Entry number 287944

    This entry is a followup to: 287552

    keyword=Central beam position ?

    The beam positions are far from zero. Do we want to run this way ?
    Musson says this is the reason that for part of the orbit the cavities
    saturate (halog 287552). It's a small part of the orbit, so it gets
    hidden when one integrates over the orbit, as the HAPPEX DAQ does;
    hence the HAPPEX DAQ shows reasonable correlation to striplines.

    Here is a snapshot of positions in run 11996. So, 2.2 mm is ok ???
