Run Plan: Nov. 9 - Nov. 10Upstream beamline commissioning and beam tune using the tagger dump (beam will not go through the Hall). The goal is to get CW stable beam to the Hall-B tagger dump, on 2C24 harp (tagger harp) achieve beam parameters routinely used in Hall-B 6-GeV era X/Y width ~150 micron, and S/N on halo counters from harp wire >10E4.
