Comparison of experimental pulse-height distributions in germanium detectors with Integrated-Tiger-Series-code predictions

Pulse-height distributions in two different types of Ge detectors have been measured for a variety of medium-energy X-ray bremsstrahlung spectra. These measurements have been compared to predictions using the Integrated Tiger Series (ITS) Monte Carlo electron/photon transport code. In general, the authors find excellent agreement between experiments and predictions using no free parameters. These results demonstrate that the ITS codes can predict the combined bremsstrahlung production and energy deposition with good precision (within measurement uncertainties). The one region of disagreement observed occurs for low-energy (<50 keV) photons using low-energy bremsstrahlung spectra. In this case the ITS codes appear to underestimate the produced and/or absorbed radiation by almost an order of magnitude.<
