Shift Summary:
------------------------------------------------------------
1. Beam from 9:30 am until 1 pm. Main Magnet Supply Problem
aborted rest of shift.
2. Run 5407, 223K trigger 1, completed data taking at 1/5 field.
Run 5408, ~70K at 1/3 field
3. Run 5420 at this field had about 33K trigger1, but with DAQ
lights T5-map and T3-map flashing.
4. RunError messages,IoServer crashes possibly linked to
high current on T5 anode 1, 29 microamps.
Lowered and raised T5 anode 1 voltage and were able to
take data in run5420 with ~33 K trigger 1.
Instabilities in anode and cathode currents in T5 possibly
linked to fluctuations in beam background.
Otherwise no detector problems.
