| This document outlines the design selection of an electromagnetic sampling calorimeter, deemed ShowerMax, which will make an independent measurement of the parity-violating asymmetry in electron-electron scattering in JLabs’s MOLLER experiment. The physics motivation for the experiment is outlined and a justification for using such a detector is given. The theory of electromagnetic calorimetry is covered along with the challenges for using a calorimeter in order to measure a parity-violating asymmetry. Next, the testing, simulations, and general decision making process for all aspects of the detector are covered. Finally, a beam test is devised in order to benchmark the simulations and test the full scale ShowerMax prototypes.
