Résumé

A novel scheme and methodology for the production, acceleration and extraction of ions, both negative and positive, for a broad spectrum of applications is investigated. The production of the plasma, from which the ions are extracted, is based on ultra-short high intensity laser beam interaction with clusters. The non-linear propagation and filamentation effects during the propagation of the ultra-short laser pulse in the clusters improve the volume ion production [1]. The selection of negative or positive ions extraction from the plasma is based on the magnetic insulation principle, where a strong external magnetic field is coupled to an accelerating electric field in a diode-like configuration [2]. The main advantages of the proposed ion source are (a) the high density of the produced ion beam and (b) the relatively small volume of production. A multi-fluid code in cylindrical geometry describes the spatio-temporal evolution of plasma species in the magnetically insulated diode configuration [3]. The code is also used to calculate the evolution of the state parameters of the plasma produced from filamentation [1]. These results enable us to investigate an improved configuration for plasma generation based on filamentation effects in (i) compact magnetic fusion devices and (ii) important applications of negative ion beams for plasma heating. The new high energy, high average power, high efficiency ICAN fiber laser [4] is a good candidate for both the plasma generation and the photoneutralization of negative ions beam. [1] Moustaizis, S.
