An Investigation of Bremsstrahlung Reflection in a Dense Plasma Focus Device
Abstract
An overview of Bremsstrahlung radiation, which is prevalent in high-temperature fusion plasmas, is given, as well as estimates for the power and energy flux to a reflector wall from a dense plasma focus device burning p-11B. From these calculations, the wall temperature and ablation rate can be calculated. The physics derived from Inertial Confinement Fusion (ICF) Hohlraum use are applicable in the case where the wall temperature exceeds 105 K, and the reemission flux is estimated for various flux levels. Provided a method could be found for decreasing the incoming flux to the wall (low Z material shields, cooling methods), multilayer structures would provide the best method for reflecting soft and hard x-rays. Experimental results from high-energy photon experiments are provided.
