Abstract
Abstract A magnet coil for a particle accelerator is formed of a plurality of turns of a conductor each composed of two yokeshaped parts of conducting material containing a central metallic tube. The tube extends from each end of the parts. The parts are so positioned that the projecting tubes engage each other, where they are welded together. The inside tube is then tested. Conducting members are then placed around the tube in the gaps between the adjacent yoke-shaped parts and are welded to the conductor members. The whole unit is then embodied in insulation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
Liquid-cooled magnet coil for a particle accelerator comprising a plurality of turns of a conductor provided with a cooling channel and surrounded by insulation, several turns being arranged in the same plane, the conductor being spliced at at least one relatively short section per turn, in which said cooling channel is lined by a metal tube which is joined by means of welding at the central part of said splice section and that along said splice section said conductor is constituted by a conductor part, formed by at least two adjacent conductive parts surrounding the metal tube which are joined at each end to the rest of the conductor.
Claim 2
Dependent Claim
109 words
Liquid-cooled magnet coil for a particle accelerator comprising a plurality of turns of a conductor provided with a cooling channel and surrounded by insulation, several turns being arranged in the same plane, the conductor being spliced at at least one relatively short section per turn, in which said cooling channel is lined by a metal tube which is joined by means of welding at the central part of said splice section and that along said splice section said conductor is constituted by a conductor part, formed by at least two adjacent conductive parts surrounding the metal tube which are joined at each end to the rest of the conductor.
Claim 3
Dependent Claim
58 words
Liquid-cooled magnet coil for a particle accelerator according to claim 1, in which the magnet coil has two splice sections per turn and the conductor is also formed between the splice sections from two adjacent parts which are held together and pressed against said tube by means of a layer of strongly prestressed insulating tape surrounding the conductor.
Claim 4
Dependent Claim
203 words
6 Method of manufacturing a liquid-cooled magnet coil for a particle accelerator which magnet coil comprises turns of a conductor provided with a cooling channel and surrounded by insulation, several turns being arranged in the same plane, each turn substantially comprising two yoke-shaped parts joined to each other, in which each yoke part is built up of a number of copper bars which together form said conductor provided with a cooling channel, arranging the bars to surround a tube arranged as a lining in the cooling channel, the tube ends projecting from the ends of the bars, after which said bars are surrounded along substantially their entire length by a prestressed insulating tape and thus brought into effective heat-conducting contact with the centrally arranged tube, after which tubes belonging to different yoke-shaped parts are joined together by welding the projecting tube ends, and the tightness of the weld is checked by introducing a pressure medium into the tubes, after which the projecting tube parts not surrounded by copper bars are surrounded by joining bars and the joining bars joined to adjacent yoke-shaped copper bars, after which the joining bars and adjacent, uninsulated parts of the yoke-shaped copper bars are furnished with surrounding insulation.
