The JLab Super Bigbite Spectrometer (SBS) program’s primary goal is to determine the elastic nucleon form factors at high momentum transfer. The SBS program includes a measurement of the neutron electric form factor, GEn, using the double-polarization technique with both a polarized electron beam and a polarized He-3 target. In order to obtain adequate statistics in the high Q2 region, the polarized He-3 target has operated with a polarization-weighted luminosity approximately a factor of three above any previous polarized He-3 target used in an electron-scattering experiment. The analysis of this experiment aims to extract GEn at Q2 values of 3.0 , 6.8, and 9.8 GeV2. This talk will include a brief introduction to form factors, specifically, GEn, a description of the major hardware subsystems crucial to running the experiment, progress on the target analysis, and finally a brief look into the early stages of data analysis.
