Abstract
In the context of Fast Ignition, the fast electron temperature is a key parameter to determine the laser-to-fast electron energy conversion efficiency. 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.Keywords
