PPC Germanium Detectors for Measuring CEvNS at the SNS

P-type point contact germanium detectors (PPCs) are a powerful tool for radiation detection, offering good energy resolution, low noise, and small energy thresholds. The COHERENT Collaboration plans to commission a 15-kg array of high purity, low background PPC detectors to measure coherent elastic neutrino-nucleus scattering (CEvNS) at the Spallation Neutron Source. Germanium will contribute an intermediate data point between cesium and argon in the ongoing measurement of the predicted N² cross section dependence for CEvNS. The superior energy resolution of PPCs will also allow for the precise measurement of the CEvNS recoil spectrum. I discuss efforts to design and construct the array within the collaboration.
