A synchrotron radiation source contains a particle track with a curved track section. A beam guiding chamber surrounding the particle track has an exit opening for the synchrotron radiation leading in an outward direction. A magnetic device has superconducting coil windings located on both sides of the particle track having a peripheral outer rim. In addition, a device for the mechanical fixation of the superconducting coil windings is provided. The fixation device has at least one support element at the peripheral outer rim of the magnetic device. The support element is located further outward than the exit opening for the synchrotron radiation and acts substantially perpendicular to the direction of the radiation. The support element is covered from the synchrotron radiation by a radiation absorber. The use of a support element provides simple and safe support for the superconducting coil windings in the area of the radiation exit opening.

Synchrotron radiation source having adjustable fixed curved coil windings

For accelerating charged particles, an acceleration path in the form of a race track is provided with straight track sections and curved track sections with which dipole magnets with curved flat coils are associated and which are provided radially outward with at least one exit opening for synchrotron radiation. According to the invention, an absorber (20) is arranged in the chambers (16) of the curved track sections (3, 4) and a support structure (60) is provided between the dipole magnets (22, 23) behind the absorber (20) in the direction of the synchrotron radiation (18). The absorber (20) can advantageously be provided with additional cooling. The support structure serves as a spacer for the superconducting dipole magnets (22, 23) of the curved track sections (3, 4). The support structure for the flat coils is thereby simplified accordingly.

Synchrotron with radiation absorber

A magnetic device is arranged in a curved section of the path of electrically charged particles of an acceleration installation around a beam guiding chamber. The magnetic device contains curved coil windings built up of superconducting rectangular conductors, which have convex outsides, concave insides as well as transition regions at the coil ends between these sides. The superconducting coil windings (4a) according to the invention are arranged at least with their winding parts (57, 58) forming the convex outsides (53) and concave insides (54) in grooves of correspondingly formed coil formers of the magnetic device, with the grooves extending downward at least approximately perpendicular to the plane (x-y plane) determined by the particle path. In addition, the superconducting coil windings (4a') in the region of their coil ends (55') are bent up saddle-shaped. With these measures the effect of undesirable conductor motions on the exactitude of the magnetic fields generated by the coil windings can at least largely be excluded.

Magnetic device with curved superconducting coil windings

A device for holding the winding housing of a superconducting magnet winding which is to be cooled to a low temperature, the winding housing surrounded by a cooled radiation protection shield, which itself is enclosed by an outer housing approximately at room temperature, includes at least one rigid tubular support element which has low thermal conductivity, arranged between the outer housing and the winding housing and connected to the radiation protection shield. In order that the holding device causes only minimal heat transfer into the cold winding housing and still permits safe transport of the warm structure, the winding housing is suspended in the outer housing by means of a poorly heat-conducting suspension device, and the tubular support element is designed to have a variable length, so that a form-locking fit between with the outer housing and the winding housing is set at room temperature. The support element is attached by means of a fastening device comprising a spring element to the radiation protection shield in such a manner that a form-locking fit with the outer housing always exists, so that as the winding housing shrinks with cooling, the support no longer contacts the winding housing and heat transfer through the support element to the winding housing is no longer possible.

Device for holding the housing of a superconducting magnet winding

A method for constructing a superconducting magnet winding which contains parallel winding layers each spaced by a separator and around the outer surface of which hardenable material is cast which is worked to a predetermined dimension after hardening, in which each winding layer is prefabricated individually and its outer surface is provided with a cast, ridge-like extension of hardenable material, and in which all cast extensions are worked down to the fit dimension after the winding is assembled, avoiding cementing of cooling ducts together in the separators.

Method for constructing a superconducting magnet winding

A superconductor structure with a stabilized superconductor, is surrounded by a jacket of a reinforcement material, comprising a preprofiled metal sheet which is bent around the superconductor and contains strip-like zones which extend in the lengthwise direction of the conductor and are in contact with the superconductor, and strip-like zones in between which are spaced from the surface of the superconductor, with filler strips of predetermined thickness arranged in the channel like outer depressions of the jacket.

Superconductor structure and method for manufacturing same

A shorting element for closing a superconducting current path using contacts of a stabilized superconductor material with the contacts being brought together through the use of a mechanical actuating device, in which the contact surfaces of the contact elements are brought into contact using a pneumatic and/or hydraulic means operated by a pressure medium fed into the interior of at least one spring bellows. The shorting element, which is particularly useful in shorting superconducting magnets, is of a simple design, operationally reliable, and results in small coolant losses from the addition of heat through the shorting element.
