Description
The Super Bigbite project encompasses a set of experiments which utilize the principles of large acceptance, highly reconfigurable magnetic spectrometers that aim to measure fundmental structure of nucleons at high momentum-transfer in experimental Hall A at the Thomas Jefferson National Accelerator Facility in Newport News, Virginia. These experiments push the bounds of what has been previously experimentally accessible with newly developed, state of the art equipment and the newly upgraded $12~\mathrm{GeV}$ CEBAF polarized electron beam, focusing on measuring three of the four elastic nucleon form factors to high precision at large $Q^2$. Additionally utilizing this equipment, measurements of transverse momentum distributions of the neutron through semi-inclusive deep-inelastic scattering in the channels $\vec{n}(e, e'\pi^\pm (K^\pm ))$ have also been approved as well as a measurement of tagged deep inelastic scattering. An overview of the apparatus, experimental program, and impact on the understanding of nucleon structure will be presented.
