Prototypes of radiation detectors for clinical dosimetry were constructed using commercially available synthetic diamond. Polished diamond plates of detector grade and standard quality were used. The metallization scheme was a typical Ag-Ag contact for the detector grade diamond and a new metallization technique for the standard quality diamond. This was for determining which detector is more appropriate for radiotherapy dosimetry needs. The detector signal was analyzed as a function of bias voltage in the 0-500 V range both in absence of radiation and in a Co-60 gamma-ray beam. The response linearity was assessed in Co-60 gamma-ray beam for dose-rates in the range from 0.2 to 1.2 Gy min-1. Pre-irradiation effects were also investigated. Signal rise time, signal stability and reproducibility are reported and discussed. © 2010 Elsevier B.V.
