Abstract: The invention comprises a solid material that is an electrical conductor in a single direction which comprises an amorphous glass matrix containing a plurality of microscopically thin metal filaments, all of which are oriented in the direction of conductivity and extend to or near the surfaces of the solid material. This directionally conducting material is produced by subjecting a metastable glass supersaturated with metal to directed ionic radiation. On irradiation parallel microscopic holes or pores are formed which become filled with molten metal during tempering, which cool to form metallic dipole filaments. The thickness of the material and the angle of irradiation may be selected to produce dipole filaments of lengths appropriate to act as antennas for electromagnetic radiation of wavelengths from about 0.1 micron to about 1 mm. The direction of conductivity, i.e.

Abstract: A high current ion source for generating ion beams from gases and non-volatile materials which comprises a furnace-cathode unit for generating vapor to be ionized, a major source unit for ionizing the vapor generated in the furnace-cathode chamber and an extraction unit for removing the ions from the major source unit. The three units are removably sealed to each other by vacuum-tight seals. The furnace-cathode unit includes a furnace chamber, the major source unit includes a discharge chamber and the extraction unit a source outlet electrode. Connecting means couple the furnace chamber to the discharge chamber, and suspension means are provided for suspending the components from surrounding flanges.

Abstract: Method for producing nuclear traces, or microholes originating from nuclear traces, from a single ion or a countable number of ions in a solid body by means of an accelerator, e.g. heavy ions in a heavy ion accelerator. A widened or attenuated beam or ions is directed onto the surface of a solid body via a preliminary aperture to cut out any non-required particles. The impinging of an individual particle, after or before passage through the solid body, is determined directly and depending of this determination, other particles which might possibly pass through the aperture are prevented from doing so.

Abstract: A Faraday dish for making measurements at a beam path of a heavy ion accelerator comprising a supporting structure, a hollow outer conductor and an inner conductor coaxial with the outer conductor. The outer and inner conductors each have a first portion with an open end facing the beam and a second portion perpendicular to the beam path.
