** <font color=blue>In order to do above program, when CW beam is established, Hall-B beam halo counters and harps (2C21 and 2C24 or tagger) must be calibrated first. So it may take multiple harp scans to set harp motion limits and halo counter PMT gains. With any issue contact Beamline Expert or RC. </font> | ** <font color=blue>In order to do above program, when CW beam is established, Hall-B beam halo counters and harps (2C21 and 2C24 or tagger) must be calibrated first.
