Abstract: An X-ray source apparatus contains an X-ray target which emits X-ray when bombarded with electrons from an electron source. A strong magnetic field, e.g. from a superconducting solenoid, having curved lines of magnetic flux interlinks the target and electron source. The magnetic field has sufficient strength over the entire electron path of travel to constrain the electrons emitted from the source with components at angles to the magnetic field to execute helical paths about the field lines to the target. An aperture means is positioned to block the straight line paths between the source and the target but permits the passage of substantially all electrons traveling along the lines of flux.

Abstract: A superconducting electronic device utilizes a weak link (Josephson junction) between two regions of superconductor material. A method of making such a device having a granular structure consists of taking a substrate with a predetermined grain size, and forming a thin film of superconducting ceramic upon it. The film adopts the grain size and structure of the substrate, and the film is then processed to form two relatively large areas of granular film connected by a thin link which contains a single grain boundary which acts as the weak link.
