X-ray dosimetry with low-capacitance silicon detector

The paper presents a low capacitance, low reverse current, suited for x-ray dosimetry at room temperature. The detector is a `drift chamber' type, with a transversal field collection of charge carriers. Based on the low noise performance of the detector and the first stage of electronics, a pocket size x-ray dose ratemeter is proposed, for the 10...60 keV energy range.
