Operator: tancredi
Very quiet shift, occassionally a few crate trips
_ running pol D2, spin angle is 32 deg, expected 45 or more. Cell temp steady at 116.5 +- 0.2 K.
_ Noticed almost linear increase of beam lifetime with time (+20 % or 5 min in last 24 hrs) however QE d(eep)n yield stayed constant, ca 9.5 ev/C
_ Polarization also constant -w ithin erors - over same time range. Average hP_z since hall access yesterday amount ot 38 +-3 % (L sector) and 40 +-2 % (R-sector) (runs 13605-13627, 2 have not crunched yet), so target vector polarization seems to be about 60 +- 5 %
_ Updated spin angle in macro show_deep_asym.C. At any good rate the macro
to use is macros/Deuterium/DEEPLIB/show_deep_asym_all.C in case you
don't remember what it looks like..
_ Note: on daq node, elog page is really "file:///elog/index.html", not blast.lns.mit.edu/elog
