Characterization Techniques for the Large Silicon Detectors Used in the Nab Experiment

The Nab experiment aims to probe the weak nuclear force by performing correlations to high precision measurements of neutron decay by coincident detection of the electron and proton decay products using large highly segmented diode silicon detectors. The detector performance and proton response were evaluated using a low energy proton beam facility at the University of Manitoba. Here, we present a calibration analysis pipeline tool which has been developed for Nab from data obtained at Manitoba for 113Sn and 109Cd sources, providing a characterization of the detector energy response for electrons. We present the status of the calibration results which are consistent with an expected linear electron energy response. This pipeline provides a solid basis for interpreting a parameter critical to the Nab experiment: the proton energy response. We also present an application of the calibration results for additional analyses of detector properties.
