    keyword=BigBite Thresholds reset

    When I turned off bbcamac1 all the thresholds were wiped even for the dE 
    and E plane discriminators.  I reset the wire chambers to 3.5 and 4.0 V,
    respectively.  I then set the E, dE and dEtrigger to -50 mV.  When I 
    checked this morning the scintillator planes were already at -8 mV.  This 
    is probably from the other day when I unplugged bbcamac1.  In any case, we
     have been taking data for the the scintillators with very low thresholds 
    up until today.
    Whenever bbcamac1 is power cycled, we need to remember to reset all 
    thresholds for BigBite detectors.  I am not sure if this is true for the 
    HAND LeCroy 4413 modules, which are on bbcamac2 and bbcamac3.
