Bremsstrahlung characterization at PBFA Z

Summary form only given, as follows. Sandia National Laboratories has developed a >1 MJ soft X-ray source using Z-pinch implosions. The machine generates a high energy (>2 MeV) bremsstrahlung background that affects diagnostic development and may preheat the fuel in proposed inertial confinement fusion experiments. In this presentation we will show calculations of the bremsstrahlung spectrum and the estimated heating of the fuel. Measurements of the bremsstrahlung as a background noise source will also be discussed.
