The Spin Asymmetry on the Nucleon Experiment (SANE) at Jefferson Lab measures proton spin observables A{sub 1}{sup p}, A{sub 2}{sup p} and structure functions g{sub 1}{sup p} and g{sub 2}{sup p} over a broad range of Bjorken scaling variable x from 0.3 to 0.8, for four-momentum transfers ranging from 2.5 GeV{sup 2} to 6.5 GeV{sup 2}. Inclusive double spin asymmetries were measured by scattering 4.7 and 5.9-GeV longitudinally polarized electron beam off a polarized solid NH{sub 3} target, in both parallel and near-perpendicular configuration. Scattered electrons were detected using a novel non-magnetic detector array with 194-msr acceptance. This paper presents the physics motivation for the experiment, the detector performance, and the latest status of the ongoing data analysis.
