Paper Abstract

A class of wide band-gap semiconductor offers an attractive alternative to Si and X-ray diode (XRD) detector technologies for x-ray detection in Inertial Confinement Fusion (ICF) experiments. Because diamond presents high thermal conductivity, resistance and breakdown field, fast charge collection, low leakage current, wide band-gap, low dielectric constant, large carrier drift velocity and outstanding radiation hardness. Using chemical vapor deposited (CVD) technology, 1 mm×1 mm×2 mm, 1 mm×1 mm×3 mm diamond was synthesized. And the detectors were fielded with metal-semiconductor-metal structure. Characteristics of the detectors have been studied on a pulse laser equipment. The results indicate that the rise time and FWHM of the detector reach 60 ps and 120 ps respectively.
