Abstract

One of the future plans at Jefferson Lab is running electron scattering experiments with large acceptance detectors at luminosities $> 10^{37}cm^{-2}s^{-1}$. These experiments allow the measurements of the Double Deeply Virtual Compton Scattering (DDVCS) reaction, an important physics process in the formalism of Generalized Parton Distributions, which has never been measured because of its small cross-section. The luminosity upgrade of CLAS12 or the SOLID detector makes Jefferson Lab a unique place to measure DDVCS. One of the important components of these high luminosity detectors is a tracking system that can withstand high rates of $\approx 1MHz/cm^{2}$. The recently developed Micro-Resistive Well (uRWELL) detector technology is a promising option for such a tracking detector by combining good position resolutions, low material budget with simple mechanical construction, and low production costs. In this proceeding, we will discuss recent developments and studies with uRWELL detectors at Jefferson Lab for future upgrades of the CLAS12 detector to study the DDVCS reaction.
