Soft x ray detection with diamond photoconductive detectors
Abstract
Photoconductive detectors fabricated from natural IIa diamonds have been used to measure the x ray power emitted from laser produced plasmas. The detector was operated without any absorbing filters to distort the x ray power measurement. The 5.5 eV bandgap of the detector material practically eliminates its sensitivity to scattered laser radiation thus permitting filterless operation. The detector response time or carrier life time was 90 ps. Excellent agreement was achieved between a diamond PCD and a multichannel photoemissive diode array in the measurement of radiated x ray power and energy.
