The characterisation of a detectors response in the kilovoltage range is necessary to understand its response to scattered radiation in the megavoltage range. Scattered radiation is absorbed in the detector by the highly Z-dependent photoelectric process. Measurements of diamond detector response to highly filtered quasi-monoenergetic X-rays and synchrotron-generated monoenergetic photons have been performed revealing effects that relate to the presence of copper and silver used to form electrical contact with the crystal. A three-component model of energy absorption, utilizing tabulated cross-sections for C, Cu and Ag, is proposed and a calculation of phantom scatter factors for diamond detector is given.
