Abstract: The present invention relates to a lens system for particle radiation devices, particularly electron microscopes, which includes means for adjusting the particle beam, a plurality of superconducting cryogenically cooled magnetic lenses, a cryostat in which the lenses are received and a central supporting tube in the cryostat on which the lenses are mounted. An electron microscope produced according to the present invention is substantially free from thermal drift phenomena, is substantially insensitive to mechanical vibrations, can be readily protected against the influence of external magnetic fields, and can be assembled and disassembled conveniently for cleaning or exchanging parts.

Abstract: A RELATIVELY DUCTILE HARD-SUPERCONDUCTIVE MATERIAL AND A METHOD OF PRODUCING THE SAME WHEREIN A MATRIX MATERIAL (I.E. CR) CONTAINING AN EMBEDDED MATERIAL (I.E. NB) CAPABLE OF COMBINING WITH O2, N2 OR MIXTURE THEREOF TO FORM A HARD-SUPERCONDUCTIVE COMPOUND IS ANNEATED IN A GAS OF O2, N2 OR A MIXTURE THEREOF AT TIME-TEMPERATUREPRESSURE CONDITIONS SO THAT THE GAS COMBINES WITH THE EMBEDDED MATERIAL TO FORM A HARD-SUPERCONDUCTIVE COMPOUND WITHIN THE MATRIX MATERIAL.

Abstract: A magnetic lens device for corpuscular ray apparatus to operate under vacuum is equipped with a pair of tubular shielding cylinders of superconductive material coaxially surrounding the lens axis and spaced from each other along said axis. Cryogenic means are thermally connected with the cylinders, and lens windings surround the cylinders for generating a magnetic field. The respective cylinders terminate in end faces directed toward each other and defining between each other a lens gap in which the cylinders concentrate the field near the axis. According to the invention proper, the shielding cylinders comprise respective end portions of superconductive material of higher currentcarrying capacity than the remaining portion of each cylinder, said end faces at said lens gap being formed by said respective end portions.
