High mobility single crystal diamond detectors for dosimetry: Application to radiotherapy

The X-ray detection performance of polycrystalline CVD diamond with pulsed laser deposited carbon electrodes

“…In an other report [25] the SNR was 776 for single crystal diamond with a contact of nickel on one side and gold on the other side, which is consistent with the value of Poly-Pt.…”

Toward Pulse by Pulse Dosimetry Using an SC CVD Diamond Detector

“…Schottky diodes are expected to have very good linearity. Dose-rate linearities have been measured in singlecrystal CVD diamond detectors by a number of groups [6], [9], [22]- [28], several of whom determined a significant nonlinear response as a function of dose-rate [6], [9], [23], [27], [28]. A variety of methodologies were used, including varying the PRF, varying the source current in the case of X-ray sources, and varying the source to detector distance, which is the method that has been used here.…”

The effect of fast neutron irradiation on the performance of synthetic single crystal diamond particle detectors

“…Our results show that bothelectron and hole charge transport -are increasingly compromised by charge trapping and the subsequent build up of space charge that is characteristic polarisation processes, with increasing absorbed neutron dose. Further investigations, like transient induced current studies [5,19,29] are needed to understand the effects of polarisation (i.e. changes in charge carrier velocity) and priming, (i.e.…”
