"Jlab SBS Program to Measure Nucleon Elastic Electromagnetic Form Factors at High Q2 and âGas Electron Multiplierâ Detectors"Anuruddha Rathnayake , University of Virginia - Department of Physics [Host: Nilanga Liyanage]
ABSTRACT:
In the fall of this year in September, the Jlab Hall-A SBS program is sched-uled to start running. The primary goal of the program is to measure elastic-electromagnetic form factors of the nucleon with high precision at high Q2 values. The knowledge of the electromagnetic form factors are essential for our understanding of the structure of the nucleon. The concept of the Hall-A SBS (Super Bigbite Spectrometer), which has a large solid angle acceptance (∼ 75 msr) and the capability to operate at high luminosity, relies on Gas Electron Multiplier (GEM) detectors for particle tracking. In this talk, I will talk about how the GEM detectors will be used in the SBS program, and the commissioning activities of the UVA-built GEM detectors that are underway at the Jefferson Lab, in order to make them ready for the upcoming experiments. Also, I will briefly talk about the Jlab-SBS program with a special focus on its very first experiment - GMn : precision measurement of the magnetic form factor of the neutron up to Q2 = 13.5 (GeV/c)2 using the ratio method. |
