A JLab PAC-25 Proposal to Measure GEp/GMp Using a Polarized Target

Measurement of G_E^p/G_M^p via Double Polarization Asymmetries

We are proposing an experiment to measure the proton form factor ratio G_E^p/G_M^p up to Q²=5.6(GeV/c)² using a 5.562 GeV polarized beam and a polarized proton (NH3) target in Hall C. Various versions of the updated proposal can be downloaded below. Please send me comments and suggestions by May 23 so I can make it to the May 24 submission deadline.
