title: Determination of the energy response of closely tissue-equivalent diamond dosimeters for radiotherapy dosimetry.
abstract: A monoenergetic X-ray syncrotron source was used to determine the energy response of a diamond detector in the range 5-25 keV, clarifying the elemental composition of the detector. The response is shown to be influenced by the detector housing and electrical contacts. A model for the energy response of the detector is determined that is valid in the 5 keV-15 MeV with an accuracy of 5% and therefore can be used to correct the dosimeter response to low-energy and scattered radiation.
