This phase is designed to probe muon to electron conversion 100 times better than the current limit. The experiment will achieve this sensitivity by directing a high intensity muon beam at a stopping target. The detectors probe the resulting events for the signal 105 MeV electron from muon to electron conversion. A boosted decision tree (BDT) algorithm has been developed to find this signal track. This BDT is used to combine energy deposition and timing information with a reweighted inverse hough transform to filter out background hits. Results show that using a BDT significantly improves in background hit rejection when compared to traditional, cut-based hit rejection methods. At 95% signal hit retention, the BDT is able to remove 98% of background hits.
