ERR Hypernuclear

Hall C Hypernuclear Experimental Readiness Review 2024

ERR for The experiments E12-24-013, E12-24-011, E12-24-003, E12-24-004, and run group E12-20-013A/E12-15-008A. All experiments use a common beamline. target scattering chamber and target ladder. They all use the High-Resolution Electron Spectrometer (HES) and High-Resolution Kaon Spectrometer (HKS). The HKS and HES magnets, support structure and detectors were used in earlier experiments that ran Hall C. A new feature is Pair Charge Separation magnets (PCS). There are two of these magnet pairs. One of the PCS will be part of the HES magnet setup and another PCS is part of the HKS magnet setup. The run group E12-20-013A/E12-15-008A can take data simultaneously with the other experiments using the ENGE magnet in coincidence with the HKS.
