Description of Shift:

run spill time comment
15723 08:35 end run after 13 hours.
                   go to muon mode, took sereral short runs
                   to adjust UCAL gains up by a factor of 5.
                   and lower analog sum threshold to 30 mV.
15727 09:30 take KAMI_HADRON data with higher UCAL gains.
                   events are completely dominated by lower energy
                   junk, same with 20 inch Be absorber.
            10:15 go back to original UCAL gains.
            10:30 Bob H. and Anatoli make access to remove UCAL16
                   and move BAG into east beam in front of UCAL.
15732 11:55 run KAMI_HADRON with various absorbers.
15735 12:45 start long minbias run with 20 inch Be absorber.

   Plan is to continue this minbias run until tomorrow morning at
about 6:30 when people will enter NM2 to move magnets so as to
go to 15 mrad angle.
