Potential of Kα radiation by energetic ionic particles for high energy density plasma diagnostics

Abstract

In this paper, potential of diagnostics with the use ofKα radiation for an energy deposition process from an intense ion-beam to background plasma is considered quantitatively.Kα radiation is a good candidate for the purpose. The wavelength ofKα radiation is varied according to the charge state of an emitter atom, and the diagnostics spatially resolved with radiations from various kinds of charge states can give us a profile of plasma temperature in a target material. For the calculation ofKα yield, an atomic population kinetics code is developed, and the result shows thatKα radiation has potential to get information of a plasma profile heated by an intense ion-beam.
