Abstract 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.

Abstract The GEp-III and GEp-2 γ experiments, carried out in Jefferson Lab’s Hall C from 2007–2008, consisted of measurements of polarization transfer in elastic electron–proton scattering at momentum transfers of Q 2 = 2 . 5 , 5 . 2 , 6 . 8 , and 8.54 GeV 2 . These measurements were carried out to improve knowledge of the proton electromagnetic form factor ratio R = μ p G E p ∕ G M p at large values of Q 2 and to search for effects beyond the Born approximation in polarization transfer observables at Q 2 = 2 . 5 GeV 2 . The final results of both experiments were reported in a recent archival publication. A full reanalysis of the data from both experiments was carried out in order to reduce the systematic and, for the GEp-2 γ experiment, statistical uncertainties. This technical note provides additional details of the final analysis omitted from the main publication, including the final evaluation of the systematic uncertainties.
