Description
Large-area Micro-Pattern Gas Detectors (MPGDs) have become key components in the tracking systems of many major ongoing and future electron scattering experiments at Jefferson Lab (JLab). Various large-area Gas Electron Multiplier (GEM) trackers have been recently developed and constructed for three highly ranked experimental programs at JLab: the Super Bigbite Spectrometer (SBS), PRad-II, and MOLLER. GEM trackers are also considered the primary choice for the future SoLID physics program at JLab. Due to their excellent position resolution, low material budget, and simple mechanical construction, large-area Micro-Resistive Well ($\mu$RWELL) detectors have emerged as highly promising candidates for upgrading the CLAS12 forward tracking system to support operations at luminosities as high as $\mathrm{2\times 10^{35}\ cm^{-2}s^{-1}}$ in Hall B. By combining high-granularity tracking with transition radiation capabilities for particle identification, the GEM-based Transition Radiation Detector (GEM-TRD) has been proposed as a key component for improving electron-pion separation in the GlueX experiment in Hall D at JLab. This talk will discuss the challenges in the design, fabrication, and operation of large-area GEM trackers for high-luminosity experiments at JLab, as well as ongoing R$\&$D efforts on large-area $\mu$RWELL and GEM-TRD technologies for future JLab experiments.
