Apologies. There was a correction to the second abstract. It should read as
follows.
The Spin Asymetries of the Nucleon Experiment (SANE) is an inclusive
measurement of the parallel and near-perpendicular double spin asymmetries
of the proton that provides access to the spin observable, A1p and structure
functions, g1p and g2p. The experiment ran in early 2009, using Thomas
Jefferson National Facility's polarized electron beam and the University of
Virginia's polarized frozen ammonia target in Hall C, collecting data in a
Q^2 region from 2.5 to 6.5 GeV^2 and a Bjorken x region of 0.3 to 0.8.
Particle detection was accomplished using the Big Electron Telescope Array
(BETA), a novel non-magnetic detector array with a 194 msr acceptance.//
The experimental motivations and goals will be discussed in the context of
current world data of the proton spin structure functions. Th experimental
methods will also be presented along with an overview of the analysis status
and results. Current collaboration analysis effort is focused primarily on
the proton spin structure functions g1 and g2, but also includes elastic and
inelastic asymmetry data taken with the Hall C High Momentum Spectrometer in
both single arm mode and in coincidence with BETA.
