| Publication Abstract: | The electromagnetic form factors of nucleon are essential for understanding the nucleon. The Super Bigbite Spectrometer (SBS) at Thomas Jefferson National Accelerator facility (TJNAF) was proposed to perform a series of high precision nucleon form factor experiments at large momentum transfer. The SBS will be capable of operating at high luminosity and provide a large solid angle acceptance. A set of large Gas Electron Multiplier (GEM) detectors, each with an active area of 60?200 cm2 was commissioned for a novel neutron polarimeter based on elastic and charge-exchange recoil proton detection. These GEM chambers are expected to provide a position resolution of ? 70 ?m,while operating in a high rate conditions up to 1 MHz=cm2. This thesis will outline an overview of SBS nucleon form factor experiments, commissioning activity, and performance of the GEM detectors with cosmic ray data. |
