The electromagnetic form factors of the nucleon are essential for our understanding of the structure of the nucleon. Precision measurements of nucleon form factors is a fundamental part the Je erson Lab experimental program. The 12 GeV beam upgrade and the newly designed Super BigBite Spectrometer make possible a new generation of experiments to measure nucleon form factors with high precision at high Q2 values around 10 GeV2. The concept of the Super BigBite Spectrometer, which provides large solid angle and the capability to operate at high luminosity, is based on new Gas Electron Multiplier (GEM) detector based particle trackers. The SBS GEM chambers are expected to provides a good position resolution of 70 m, while operating in high rate conditions up to 0.5 MHz=mm2. A set of 40 GEM detectors, each with an active area of 60x50 cm2, has been built in the GEM detector lab at UVa for the the proton polarimeter trackers of SBS. This seminar will present an overview of SBS nucleon form factor experiments and will report on the Research, development and testing of SBS GEM chamber data acquisition system which is essential to make those high rate experiments possible.
