Spin Asymmetry on the Nucleon Experiment

ORAL

Abstract

The Spin Asymmetry on the Nucleon Experiment (SANE) is a measurement of the spin structure function $g^{p}_{2}$ and $A^{p}_{1}$ over a broad range of Bjorken scaling variable \textit{x} from 0.3 to 0.8, for four-momentum transfers from 2.5 GeV$^2$ to 6.5 GeV$^2$. The experiment measured inclusive double spin asymmetries using TJNAF polarized electron beams of about 4.7 and 5.9 GeV energies,scattered off UVA solid polarized NH$_{3}$ target. The experiment took place from January to March of 2009. We will discuss the physics motivation for SANE and current status of the analysis, energy resolution and kinematic coverage.
