Diamond dosimeters for intense ionizing radiation were assembled by developing ohmic contacts on single-crystal high-purity diamond films. Leakage electrical resistivity of the order of 1014 ? cm was measured. Devices were tested with a low-intensity 17.48 keV x-ray beam to probe their maximum sensitivity and the minimum detectable dose-rate. Diamond detectors provided a linearity coefficient to x-ray dose-rate of 1.023±0.07, whose dependence on operative bias voltage is here analyzed.

Abstract
Diamond dosimeters for intense ionizing radiation were assembled by developing ohmic contacts on single-crystal high-purity diamond films. Leakage electrical resistivity of the order of 1014 ? cm was measured. Devices were tested with a low-intensity 17.48 keV x-ray beam to probe their maximum sensitivity and the minimum detectable dose-rate. Diamond detectors provided a linearity coefficient to x-ray dose-rate of 1.023±0.07, whose dependence on operative bias voltage is here analyzed.File in questo prodotto:
