Abstract

To obtain a beam of well-collimated neutral particles at the exit of the charge exchange box (2) of cylindrical shape and with axis Oz which is entered by a beam of primary ions (F1) consisting of Ar<+> ions, these ions are passed through a series of grids (V1, V2, V3, V4) raised to negative potentials. These grids are surrounded by argon. The following reaction therefore takes place: Ar<+> + Ar<0> -> Ar<0> + Ar<+> The neutral jet (F2) results from the neutralisation of the jet of primary ions (F1). The electrical field @ has the effect of subjecting the charged ions of the beam (F1) or the secondary ions which have undergone a charge-exchange collision to a force parallel to the axis Oz. The divergence of the beam (F2) at the exit is therefore reduced. <IMAGE>
