Abstract

A(γ,n) reaction based hard X-ray spectrometer with energy range from 4 MeV to 30 MeV has been developed for Fast Ignition related experiments. The hard X-ray spectrum is indirectly measured by counting neutrons generated via photo-nuclear reaction from various materials. The performance was evaluated by using a linear accelerator facility, and the obtained results are in good agreement with Monte-Carlo simulation.
