Ion beam effects on K-shell emission from high temperature plasma on PBFA II

摘要

K-shell emission from H-, He-, and Li-like ions can be used to diagnose electron temperature and density conditions in inertial confinement fusion plasmas. Interpretation of that emission in the ion beam interaction region on PBFA II (Particle Beam Fusion Accelerator II) is complicated by the presence of the intense ion beam. The author has added ion-beam ionization and excitation (as well as the inverse processes) to the RATION code. The ion beam is assumed to be monoenergetic and fully ionized. The ion-beam ionization rates are derived from scaled values of the ionization cross sections. The ion-beam excitation cross sections are scaled from the electron-excitation cross sections. All inverse processes are obtained from detailed balance.
