Abstract

In this paper, potential of diagnostics with the use of Kα 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 of Kα 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 of Kα yield, an atomic population kinetics code is developed, and the result shows that Kα radiation has potential to get information of a plasma profile heated by an intense ion-beam.
