    keyword=Swapped out PMT#12 in BigBite Cerenkov

    I swapped out the UV glass 5" PMT of Bogdan's (a spare for the HRS gas Cerenkov) that was installed back in February. The replacement is a 4578B quartz-face PMT. 
    Previous PMT:     ser # 60311, Model 4572B  (brand new UV glass PMT)
Replacement PMT:  ser # 112, Model 4578B  (brand new UV glass PMT)
    The PMT is awaiting survey so it can be released from the Hall.
