“…A FORTRAN routine to model inclusive pion production by J. O'Connell [38] was updated using photoproduction cross section data from the Yerevan Physics Institute [39] to improve the cross section reproduction to better than 15% in the kinematics of interest. The updated pion production model also displayed good agreement when compared to charged pion electroproduction data [40]. The asymmetry of the pair-symmetric background, A π 0 , was estimated from fits to charged pion, parallel and transverse, asymmetry data taken on polarized 15 NH 3 in SLAC experiments E143 and E155x.…”

The Spin Asymmetries of the Nucleon Experiment (SANE) performed inclusive, double-polarized electron scattering measurements of the proton at the Continuous Electron Beam Accelerator Facility at Jefferson Lab. A novel detector array observed scattered electrons of four-momentum transfer 2.5 < Q 2 < 6.5 GeV 2 and Bjorken scaling 0.3 < x < 0.8 from initial beam energies of 4.7 and 5.9 GeV. Employing a polarized proton target whose magnetic field direction could be rotated with respect to the incident electron beam, both parallel and near perpendicular spin asymmetries were measured, allowing model-independent access to transverse polarization observables A 1 , A 2 , g 1 , g 2 and moment d 2 of the proton. This document summarizes the operation and performance of the polarized target, polarized electron beam, and novel detector systems used during the course of the experiment, and describes analysis techniques utilized to access the physics observables of interest.
