Simulations for Silicon Strip Detector Calibration and Code Comparison

For studies of beta-delayed proton emission of rare isotopes in the astrophysical rapid proton capture process, accurately calibrated detection devices are vital. Simulations are necessary to interpret the signals from various calibration sources and methods, and to analyze experimental data from beta-delayed proton emission. Here both the MCNPX (Monte Carlo N-Particle transport) and GEANT4 (GEometry ANd Tracking) simulators have been used in conjunction with experimental data from calibration sources to energy calibrate three double-sided silicon strip detectors (DSSDs). This study includes the analysis of various systematic effects, such as detector geometry, source energy, source position, and particle number, with a particular emphasis on their relation to energy deposition spectra. Possible explanations for discrepancies between each code and the data will be given. The results of these simulations will be used in the study of the beta-delayed proton emission of $^{69}$Kr at the National Superconducting Cyclotron Laboratory at Michigan State University.
