"GEANT 4 simulation prep for Bethe-Heitler experiment"
ABSTRACT:

A measurement of charge asymmetry in Bethe-Heitler (BH) pair production using the High Intensity Gamma-Ray Source at the Tri-Universities Nuclear Laboratory (TUNL) has been approved and is undergoing preparation.  These preparations include theoretical computation, support and target construction, as well as detector testing and simulation.  A GEANT4 simulation has been created in order to optimize the experimental setup, to make predictions of statistics, and to identify systematic uncertainties. Following a brief introduction about the physics and the experimental preparations, the following will be discussed: 1) relationship of the simulation to the BH experiment and their difference, 2) basic simulation process for the experiment, 3) simulation results for various virtual detectors, 4) results including the charge asymmetry computed from simulations, 5) unresolved questions regarding the simulation results.
