Commissioning of a Compton-Scattering-Based Gamma Ray Source

POSTER

Abstract

Recently a Compton-scattering based gamma-ray source, in which a high-intensity laser scatters off a high-brightness electron beam and emerges as a narrow-band gamma-ray beam, has been commissioned at Lawrence Livermore National Laboratory. Operating at energies from 0.1 to 0.9 MeV, the source produces fluxes upwards of $10^6$ photons/sec with a brightness of $10^ {15} $ photons/s/mm$^2$/mrad$^2$/0.1\% BW. Presented here is a discussion of the design and performance of the laser and electron subsystems that are used to drive the source, and an overview of the parameters of the generated gamma-ray beam.
