Diamond ionisation chambers for dosimetry

Over the last decade, new techniques have emerged in order to grow diamond from chemical vapour deposition (CVD) techniques. Here, we concentrate on the use of these films towards individual dose monitoring applications. The energy response of a diamond dosimeter, when exposed to photons of energies ranging from 20 keV up to 6 MeV was simulated using a Monte Carlo transport code. Experimental measurements have been performed with X-rays in the 20–80 keV range in order to characterise the photo-electrical properties of the CVD film studied.
