Title:

Simulating the Energy Deposited in Ammonia from a High Energy Electron Beam

Experiments done by UNH's Nuclear Physics Group in the Slifer Lab require solid polarizable targets such as deuterated ammonia to study the inside of nucleons. Past attempts at creating polarizable ammonia have been unsuccessful due to a poor geometry of the irradiation set up. A Monte Carlo toolkit called EGSnrc was used to simulate the travel of ionizing radiation through the target material and its surroundings. Multiple different geometries were experimented with and this poster presents the results of simulations ran with three different geometries and three different beam energies for a total five distinct tests. Findings on how the geometries and beam energies effect the depth of energy deposition were consistent with previous research. New insight was gained on how the geometries can effect the radial distribution of deposited energy. Out of the five tests presented there was a best option however there is still more work to be done to find the ideal target irradiation geometry.
