Bremsstrahlung X-ray (γ-ray) emission represents an attractive alternative to measure this fundamental parameter. In this study, a single-shot high-energy γ-ray spectrometer with sensitivity ranging from 0.5 MeV to 7 MeV was developed, allowing to estimate the γ-ray spectrum in the fast ignition.}, title = {Development of Compton X-Ray Spectrometer for Fast Ignition Experiment}, volume = {9}, year = {2014} }
