[Rsidis-mgmt] time for one or two Moller measurements?

Hi all -
I checked with Jay Benesch this morning, and at 3 and 5 pass, the
expected beam polarization is pretty decent (94% of maximum at 5 pass,
80% of maximum at 3 pass, only 21% at 4 pass). We should be able to
extract beam-spin asymmetries with pretty good precision. Would it be
possible to set aside some time for a Moller measurement at each pass at
which we'd like to extract these? It would be nice to have a
polarization measurement in Hall C and not have to rely on measurements
in other halls and spin precession like we are doing for the kaonLT
paper. A Moller measurement should take less than a shift.
Cheers,
Dave
