Optimization of Particle Energy and Arrival Time Determination using GPUs for the Nab Experiment

Measurements of neutron beta decay correlation parameters yield a ratio of axial and vector weak couplings as well as test physics beyond the Standard Model. The Nab (Neutron a b) experiment will extract these parameters by coincidence detection of beta decay's protons and electrons, which includes energy and time of flight determination.  Because of the experiment's expected high data throughput in the form of digitized waveforms from pixelated silicon detectors, it is important to extract energies and times quickly and reliably. This poster will present results from timing and statistical studies using graphics processor based energy and time extraction.
