Single Crystal CVD Diamond Detectors for Hadron Physics

Abstract

We report on characterization of several single crystals CVD diamond detectors tested for the use in heavy-ion spectrometry and minimum ionizing particles time of flight measurements. An energy resolution of 16 keV (FWHM) is achieved using a 241 Am α-source, which is comparable to the energy resolution of silicon detectors. The collected charge maps, measured using 12 C micro beams confirm the excellent homogeneity of the novel material. Using low impedance broadband electronics and a transient-current technique the mobility and saturation drift velocity of electrons and holes are estimated.
