The Shower-max detector is an electromagnetic sampling calorimeter that will be used for MOLLER in order to provide a measurement of the parity-violating rate asymmetry. In order for the detector to be used, it must be characterized and understood via simulation and experimental data. The characterization of the detector was conducted in a Cosmic-ray Stand using two methods: a small coincidence trigger set up for one detector to test multiple small cross-sections and a large coincidence trigger set up for multiple detectors over the whole of the apparatus. Using these methods, it was concluded that the expected number of PEs for a detector is about 11.3 ± 0.8 photo electrons per cosmic-ray muon. Key Words: Shower-max Detector; cosmic-rays; MOLLER; Photo-electron yield; PhotoMultiplier Tube gain.
