Natural diamond detectors (NDDs) being developed for the spectrometric applications in tokamak fusion plasma experiments, have been used also for fast x-ray flux measurements and time-of-flight (TOF) electron spectrometry in laser beam-target interaction experiments on the CO2 laser installation TIR (λ=10.6 μm, E=80–95 J, τ∼14 ns). The magnetic field created in front of the detector provided separation of the signals induced by x ray and electrons. The waveform of a NDD current response has been shown to provide an information about energy spectra of the particles generated during laser beam-target interaction. Fast response time (≪1 ns), low sensitivity to visible light and x rays, high radiation resistance, and 100% charge collection efficiency of the type IIa diamond samples, make NDDs to be the optimal choice for TOF spectrometry of charged fusion products in inertial confinement fusion experiments. © 2001 American Institute of Physics.
