    Abstract: An evacuated chamber contains a source of primary ions, a charge-exchange box, the inlet of which is supplied by the primary ion source and delivers at the outlet a primary molecular or atomic beam which is at least partially neutralized, a target of the material to be ionized which intercepts the emergent primary beam from the charge-exchange box and which is of such geometry that the primary beam undergoes multiple reflections from the target, the target being placed within a chamber which is brought to a potential opposite to that of the polarity of the ions produced.

    Abstract: The panel is constituted by a heat-conducting flat metallic support plate provided with at least one absorbent surface composed of metallic tubes in the form of right circular cylinders having axes at right angles to the surface and disposed on a uniform lattice, and by right circular metallic cones each placed within the interior of one of the metallic tubes. The base of each cone is located at the intersection of each tube with the flat plate and the apex of each cone is located at a point within the interior of the tube. The external surface of each cone cooperates with the internal surface of the tube within which the cone is located in order to trap the entire radiation received by the panel.
