Data Analysis and Recovery for Damaged XEM2 Targets

The XEM2 experiment conducted in Hall C at Jefferson Lab uses magnetic-focusing spectrometers and targets struck by an electron beam to examine nuclear effects with inclusive electron scattering. Relying on 2022-2023 experimental data, our group investigates short-range nucleon-nucleon interactions and quark distributions in nuclei. During the experiment, the targets Li6, Li7 and Sn were damaged due to conducting heat poorly. To recover damaged target data for the high momentum spectrometer (HMS) that underwent rapid momentum changes, we examined data from the super-high momentum spectrometer (SHMS) which had relatively constant momentum settings. We determined the charge normalized yields with the SHMS to find the change in rate of events over time. For runs with special trigger settings we instead extracted data using the scaler-based information from the calorimeter and scintillator panels. Based on the change in rate of events, we determined that a correction factor can likely be obtained to recover damaged target data.
