Making good progress, we've completed quad centering to define
0L02-0L02 "straight" and 5D00-5D01 "PEPPo" BPM positions and saving
recoverable baseline correctors & quads for setup to FC2.
Overnight, first pass checkout of Compton integration mode performed w/
LV=off/on, varied rates and PITA. Initial results indicate analysis
code needs some modification and if successful, this checkout will
again be performed on OWL. In meantime, on DAY shift cryounit was
varied and beam momenta of 7.85MeV/c (max tested), 7.24MeV/c(max
spectrometer will transport) and 5.56MeV/c mid-range value setup. So,
good progress on learning process to set or measure the beam momentum.
SWING shift will focus on setting quadrupoles at different momentum
setup(s) to set spot size at T1 or ~T2, and if time permits first
checkout of the annihilation detectors. Also on DAY shift, three
methods to change target polarization while measuring pick-up voltages
were tested so we may choose/write down a procedure.<br>
