Hall B Optics Update
Log Number: 4497820Logbook(s): Entry Makers: jhowardBody:
Took B beam back to the Tagger to get beam diverging from 2C21 and 2C24 harps in the hopes of moving the beam profile to we can take the quads at the end of Hall B's line and squeeze the beam down to acceptable. Degaussing tagger now so we can run to their Faraday Cup and scan 2H00 harp again.
