On Shift: RK, AG

Hours of beam available at all intensities: 1.8
Hours of beam available at nominal intensity: 1.8
Hours of E799 data (special runs not included): 0.0
Hours of special runs (laser scans, muon runs...): 1.5

Accounting of lost time:

o Accelerator problems.

o Front end problems.


Tapes brought to FCC this shift: none.


Accesses during shift: none.


Runs ended this shift:

15477 - KAMI_KE3

Overview of shift:

Very poor accelerator performance. Got a little bit of KAMI_KE3 data at
the beginning of the shift and then some more at the end. Tevatron
is still in bad shape, also front end is unstable - lots of ktevana

                        -> called MCR and they fixed it.

                 0025 Stop KAMI_KE3 run 15475 to flip NM4 polarity while
                        beam is down for a while.

                 0105 Re-make L3-drivers with +BASWAP patchy flag to
                        incorporate ADC as shown at the top of p.42 (KAMI
                        Log I).
