Polarized deuterium data (run # 14687-14694) were taken with 150--215
mA beam current and 25 minutes life time. Ligit peaked around 4.7x10^-7
torr around 3 am and is now 4.4x10^-7 torr.

Only WC R24 has lowered HV (3800 V) now. Raising to 3825 V gave a trip in
13 minutes. Both the beam and WC are stable during this shift, though.

The cruncher demon claims that run # 14616 is stalled but inspecting
the crunching log file (following the Michael's messages),
spud4.bates.daq_14616.txt, I find that it is being crunched *very*
slowly due to a lot of reading error. So the crunching should be
completed soon enough.

Crunching the Saturday's data (05/03/26 A shift only) is
completed. The dilution factor is found to be,
Left : 0.653 +- 0.053
Right: 0.523 +- 0.034
