Abstract

In this paper, we report on the design and implementation of a compact and robust Compton spectrometer capable of measuring x-rays in the energy range 1 to 20 MeV. An iterative reconstruction method was employed to reconstruct the x-ray spectrum without assuming an initial distribution function. Spectral resolution was further optimized by judicious choice of composition and thickness of the electron-convertor, as well as angular acceptance into the spectrometer. A particle transport code was used to account for all instrument-related factors. Performance of the spectrometer was demonstrated experimentally by characterizing x-rays generated by high-order multiphoton Thomson scattering.
