    keyword=Shift Summary

    Relatively stable beam for much of tonight. Lost some minor time due to problems with Hall B beam delivery. Then, at 5:00, the beam died because of accelerator problems. No more beam until the end of the shift.

    FPP channels ~30-48 have low efficiency in some planes. This is not fully understood, looks like a card going bad. Since this probably requires an extensive access for troubleshooting, Mark decides that we should keep running for now.
