Definitions

  • the invention relates to a superconducting magnet system for particle accelerators of a synchrotron radiation source with a slot lying approximately in the plane of the particle path, tangentially or radially open for the exit of the synchrotron radiation and with a mechanical support device for the superconducting winding.
  • Such a magnet system is known from DE-OS 31 48 100 and from "Nuclear Instruments and Methods", Vol. 200, 1982, p. 475 to p. 479.
  • the coil configuration used in the known magnet system has a right-angled winding cross section and enables the tangential radiation exit.
  • the energy stored in the magnetic field is higher for such configurations than with a comparable shell arrangement.
  • This high stored energy must in the case of quenching, i. H. in the event of an unwanted transition from the superconducting to the normally conducting phase, be decoupled from the coil in order to prevent destruction of the coil due to the strong heating and the associated mechanical stresses.
  • the coil configuration mentioned requires a comparatively large amount of conductor material in order to implement the required magnetic field.
  • Superconducting deflection magnets are also used in the construction of large ring accelerators (e.g. HERA).
  • HERA large ring accelerators
  • G. Horlitz et al Superconducting Prototype Dipole Coils for HERA and
  • Alternatives and Improvements for Superconducting Dipole Coils for HERA Journal de Physique, Colloque C1, supplement au n ° 1, Tome 45, January 1984, pages C1- Essential details of these magnets are described in 255 to C1-262
  • the coil configuration used here has a shell-shaped winding cross section and an essentially cos 0-shaped current distribution The current distribution is designed for generating a dipole field within the winding arrangement.
  • the key element of this configuration is a clip that biases the superconducting coil.
  • the basic idea of the pretensioning principle is to compress the coil package so far by clamp elements in the de-energized state that the superconducting winding is supported with the rigidity of the clamp element when the coil is fully excited. This is necessary to prevent a conductor movement and thus a quench.
  • a bowl-shaped coil configuration with clamp elements does not allow the synchrotron radiation to exit tangentially with respect to the particle path curvature, since the particle path is surrounded on all sides by a vacuum tube and the surrounding coil arrangement with clamp elements.
  • the invention is based on the object of specifying a superconducting magnet system of the type mentioned at the outset, which has a low magnetic energy content, requires little conductor material and, when it is designed, an unfavorable vacuum pressure impregnation with regard to the training behavior can be avoided.
  • the at least one clamp element can form a structural unit with at least one tensioning element, which supports the superconducting winding in the region of the slot.
  • the clamp elements and the clamping elements will be separate, non-positively connected components.
  • the superconducting winding has a shell structure in which the coil is made from several concentric cylindrical shells. 0 winding packs are accommodated within each shell between two azimuth angles.
  • the advantage of this configuration is the low magnetic energy compared to the rectangular winding configuration.
  • the superconducting winding is designed as a block structure.
  • a block structure which is suitable in principle is given in H. Brechna: “Superconducting Magnet Systems” Springer Verlag, Berlin, Heidelberg, New York (1973) page 40, Fig. 2.1.6a.
  • the tensioning element can advantageously be hook-shaped, wherein it supports the superconducting winding in the region of the slot with a first leg and is suspended in the bracket, which essentially comprises the entire winding arrangement, with a second leg.
  • tensioning element can be seen in the fact that its cross section is U-shaped.
  • the inside of the base leg supports the winding parts directed towards the slot, and the two free legs are braced with the clamp and apply the required pressure force.
  • Pull bolts can be attached to the free leg ends for tensioning.
  • U-shaped clamping element with a further leg, which partially supplements the U-profile to form a W-profile, but the third free leg is not, or only partially, realized.
  • the second free base leg engages under the winding part, which lies in the plane of the curved particle path and on the side of the path center of curvature.
  • the tensioning element is designed in such a way that, when the magnetic field is switched on, it can absorb the attractive forces of the opposing coil halves directed towards the particle path plane and at the same time transmits the required pretension to the winding parts in order to exclude conductor movements.
  • the tensioning elements can preferably be designed such that they are part of the helium container in which the superconducting coil is located, in addition to the transmission of the prestress. Material can be saved in this way, in particular in the area of the slot, which simplifies the structural design in the slot area.
  • the clamp elements and / or the tensioning elements are preferably made of non-magnetic material, e.g. B. non-magnetic steel.
  • the magnet system can also be advantageous for the magnet system to design the clamp elements and / or the clamping elements as a magnetic yoke.
  • a laminated design of the clamp elements and / or clamping elements is preferable.
  • the clamp elements and the clamping elements can be designed as a solid yoke.
  • a structural unit of clamping elements and cryocontainer is particularly advantageous here.
  • the slot width and the arrangement of the windings are preferably matched to one another in such a way that, in addition to the dipole field, a quadrupole field, which has a focusing influence on the particle beam, is generated in the particle channel.
  • the slot can be enlarged by an optimization in this regard, so that more space is available for the clamping elements.
  • the superconducting winding is designed as a helium-transparent winding, i. that is, the insulation is designed so that helium can penetrate the winding between the conductors and cause intensive conductor cooling.
  • the superconducting winding 12 is made from several concentric cylindrical shells 13. Within each shell 13 there are 0 winding packages between two azimuth angles. There is non-magnetic filling material 14 between the winding packages, which consist of individual conductors running perpendicular to the plane of the representation.
  • This winding configuration results in an essentially cos e-shaped current distribution and is suitable for generating a dipole field. It has the advantage of lower magnetic energy compared to a rectangular winding configuration.
  • Electrons that move along the particle channel 11, which runs perpendicular to the plane of the illustration, are deflected as a result of the Lorentz force and forced onto a circular path 19. They emit synchrotron radiation tangentially to the outside (to the left in FIG. 1). The synchrotron radiation can emerge laterally from the particle channel 11 through a slot 15 and is available for physical experiments or technical applications.
  • the clamp elements 16 consist of punched magnetic sheets which are stacked to form a magnetic yoke.
  • the magnetic yoke has the shape of a circular curved cylinder composed of two halves, which forms a 90 ° arc.
  • sheets of different dimensions are required, between which there are spaces 17 which are filled with the cooling medium helium.
  • wedge-shaped stamped sheets can also be used. are used, but these are much more expensive to produce than sheets of the same material, as shown.
  • the sheets are welded together to form a unit.
  • the two yoke halves are connected to one another by tie rods 18. Due to the tension force of the tie rods 18, which can be applied with the aid of hydraulic pressing devices, the pressure required to pretension the superconducting winding 12 is generated.
  • the superconducting winding 12 is supported by tensioning elements 20.
  • the tensioning elements 20 are also laminated and complement the yoke effect of the clamp elements 16.
  • the tensioning elements 20 are essentially U-shaped.
  • One free leg 21 engages under the free part 22 of the winding 12 facing the slot 15 with a shell-shaped winding cross section 13.
  • the other free leg 23 engages behind a step-shaped recess 24 in the clamp element 16.
  • the tensioning elements 30 are prestressed. In doing so, they fulfill their task of transferring the forces of the coil to the yoke.
  • the superconducting winding 12, the clamp elements 16 and the tensioning elements 20 are surrounded by a container wall 25, within which there is liquid helium.
  • the particle channel 11, the slot 15 and the area outside the container wall 25 are evacuated.
  • the external cold shields and the outer vacuum jacket were not shown in FIG. 1.
  • the legs 21 of the clamping elements 20 facing the slot 15 are welded to the container wall 25. They thus serve to stiffen the container wall 25 in the area of the slot 15.
  • An insulation layer 26 is arranged between the winding 12 and the clamp elements 16, the thickness of which is selected on the basis of magnetic field calculations so that the homogeneity of the field in the particle channel 11 is not impaired by saturation phenomena in the material of the clamp elements 16 or the clamping elements 20.
  • the insulation layer 26 is a non-magnetic intermediate material, for example made of filled plastic.
  • FIG. 3 shows a further embodiment of the invention, the same or corresponding parts being given the same reference numbers as those from FIGS. 1 and 2.

  • the winding with the shell structure 13 is surrounded by a two-part clamp element 30 made of non-magnetic material, the two parts of which are connected to one another by tie rods 31.
  • the outer shape of the clamp element 30 essentially resembles a circular ring section with a rectangular cross section. It can be z. B. a 1/4 circle, as shown in Fig. 2, or a semicircle of the ring.
  • tensioning elements 33 which are arranged symmetrically with respect to the slot 32 and are made of non-magnetic material with an essentially W-shaped cross section.
  • the clamping elements 33 are turned parts, the axis of rotation of which coincides with the center of curvature of the particle track 19.
  • Draw studs 37 are welded to the outer free leg 34 and the middle free leg 35 of the W profile, by means of which the tensioning element 33 is connected and clamped to the clamp element 30.
  • the base leg 36 lying between the free legs 34 and 35 is pressed against the winding parts 38 directed towards the slot 32, so that the required pretensioning on the superconducting winding 12 is transmitted.
  • the cross section of the tensioning element 33 has a further free leg 39, by means of which the tensioning element cross section is approximately supplemented into a W-shape, the third free leg 39, which is located with respect to the particle path 19, not being formed symmetrically to the outer free leg 34 , but engages under the part 40 of the winding 12 pointing towards the center of curvature of the particle path 19.
