The Super-BigBite Experimental Program in Hall A at Jefferson Lab for the 12 GeV Upgrade

Description

A series of approved nucleon structure experiments that utilize a new spectrometer called Super-BigBite for Jefferson Lab experimental Hall A after the 12 GeV upgrade will be presented. These experiments will obtain unprecedented measurements of the internal quark structure of nucleons by measuring the three electromagnetic form factors, GpE, GnE, and GnM, and the single-spin asymmetry in semi-inclusive deep inelastic scattering on a polarized 3He nucleus. At the core of these experiments is the Super-BigBite spectrometer, a non-focusing large angular and momentum acceptance spectrometer that is designed to operate in environments of high luminosity up to ∼ 1038 Hz=cm2 and to be highly reconfigurable to meet a wide range of experimental needs. The large acceptance of the spectrometer allows for these experiments to obtain statistical precisions comparable to or better than previous measurements. This also allows for the form factor measurements to be carried out to unprecedentedly high Q2. An overview the upcoming experimental program goals and hardware in development will be presented.
