Chemical vapor deposited diamond detectors for soft X-ray power measurement
摘要
Abstract
Diamonds have high thermal conductivity, resistivity and breakdown field, fast charge collection, low leakage current, wide band-gap, low dielectric constant, large carrier drift velocity and outstanding radiation hardness. A class of wide band-gap semiconductor offers an attractive alternative to Si and X-ray diode detector technologies for X-ray detection in inertial confinement fusion(ICF) experiments. Using chemical-vapor-deposited(CVD) technology, 1 mm×1 mm×2 mm(type-A) and 1 mm ×1 mm×3 mm(type-B) diamonds were synthesized. The quality of the diamonds was examined by Ramma spectrum. The detectors was fielded and characteristics of these detectors were studied on a 8 ps pulse-wide laser equipment. The results indicate that rising time and FWHM of the detector system reach 60 ps and 120 ps respectively. The applications of CVD diamonds to X-ray measurement in ICF experiments will be reviewed.关键词
