Comparison of measured responses in two spectrally-sensitive X-ray detectors to predictions obtained using the ITS radiation transport code

Responses of a Ge detector and a filtered thermoluminescent dosimeter (TLD) array detector were measured at a steady-state bremsstrahlung source (the Pelletron), at endpoint energies from 150 to 900 keV. Predictions of detector response using the Integrated Tiger Series (ITS) Monte Carlo codes are found to be in excellent agreement with measured responses for both detectors. The results extend the range of validity of the ITS codes. With calibration provided by these experiments and by ITS predictions, dose-depth data from the TLD arrays can be used to estimate flash X-ray source endpoint energies.<
