We are running ABS polarized hydrogen again, after problems this morning
with one of the klystrons in the accelerator. The problems may have been
due to low water flow; cycling water valves cleared up the problem for
now. The plan is to run hydrogen at 195 mA fill current until Monday, at
which time we'll clean the nozzle and fill the superconducting
solenoids. While the nozzle is thermally cycling, we'll run empty or
unpolarized hydrogen. We also plan to take a shift of data with the BLAST
field off, and to run for a day or so at higher fill currents in
anticipation of more running in 2005.
Please keep RUNLIST-H2.2 up to date, and complete pol.log entries as a
shift's worth of runs finishes crunching.
