"The Spin Asymmetry on the Nucleon Experiment (SANE) at Jefferson Lab's Hall C"
 Slideshow (PDF)
The Spin Asymmetry on the Nucleon Experiment (SANE) will employ a revolutionary increase in Figure of Merit to obtain precise gp2 and Ap1 results at high Bjorken x. Using the highest available JLab beam energy, a 194 msr electromagnetic calorimeter will view the UVa polarized NH3 target at 8.5 times 10^34 proton luminosity. The large Bjorken x region provides an important view on proton structure where the sea quarks have been stripped away. Using measurements of these ``naked protons'' is crucial for the understanding of strong QCD and can provide a connection between experimentally measured moments of polarized structure functions and quark matrix elements calculated in lattice QCD. The experiment is scheduled to begin installation in June, and will begin taking data in October, using JLab's 5.9 GeV polarized electron beam. We will discuss the physics motivation for SANE, as well as the current status of the preparations and expected results.
