DIAGNOSTIC TECHNIQUES FOR INTENSE PARTICLE BEAM-TARGET INTERACTION USING K[MATH] RADIATION

On propose comme diagnostic les rayonnements x/Kα émis durant l'interaction d'un faisceau intense d'ions avec une cible. Les expériences proposées mettent en jeu un pouvoir d'arrêt amplifié. Les mesures de température et l'opacité de la raie Kα sont simulées en détail. Les techniques expérimentales ont déjà été utilisées pour des faisceaux intenses d'électrons. Elles sont décrites ici.Kα x rays emitted during the interaction of an intense ion beam with a target is proposed as a diagnostic. Tne proposed experiments which deal with enhanced stopping power, temperature measurements and Kα line opacity were simulated in detail. The experimental techniques were used in intense electron beam experiments and are also described here

DIELECTRONIC RECOMBINATION IN THE AVERAGE-ATOM MODEL

Autoionization and dielectronic attachment are usually omitted from rate equations for the non-LTE average-atom model, causing systematic errors in predicted ionization states and electronic populations for atoms in hot dense plasmas produced by laser irradiation of solid targets. We formulate a method by which dielectronic recombination can be included in average-atom calculations without conflict with the principle of detailed balance. The essential new feature in this extended average atom model is a treatment of strong correlations of electron populations induced by the dielectronic attachment proces
