Definitions

  • the invention relates to a magnetic deflection system for charged particles according to the preamble of claim 1.
  • the deflection radius r o is a function of the particle momentum and the magnetic field . It applies
  • the magnetic field must be as large as possible to generate small deflection radii ro.
  • a technically feasible limit is 1.8 T. Higher fields can be reached with superconducting coils.
  • bracket elements are known from DE-PS 35 11 282. It describes a superconducting magnet system for particle accelerators of a synchrotron radiation source, in which the winding surfaces of the coils are arranged parallel to the nominal path plane and the windings cross the particle path.
  • the invention is based on the object of specifying a magnet concept for the magnetic deflection system mentioned at the outset, which can be implemented while reducing the design effort and which simplifies the use of superconducting coils by means of simple production technology.
  • the advantages achieved by the coil arrangement according to the invention are essentially to be seen in the fact that the coils can be manufactured according to the pretensioning principle, in that the conductor is wound with tensile stress in conventional technology and the winding packages at the magnet ends are not guided over the particle path.
  • a sufficiently large gap is available for leading out the synchrotron radiation without having to do without clips, if these should not be superfluous anyway due to the winding technology.
  • 1 is a 3-dimensional representation of a magnet system consisting of 4 coils
  • Fig. 2 shows a section in the (x, y) plane of Fig. 1 and Fig. 3 is a winding package consisting of a double pancake.
  • the magnetic deflection system consists of 4 coils 1, 2, 3, 4, the spatial arrangement of which can be seen from the (x, y, z) coordinate system shown.
  • the nominal path plane SE lies in the (x, z) plane, in which the deflection path between the coils and parallel to them passes through the coordinate jump.
  • the winding surfaces with the curvature r ⁇ ro adapted to the nominal path are aligned perpendicular to the nominal path plane SE.
  • Fig. 2 shows a section through the coil system in the (x, y) plane.
  • the area Ao spanned by the magnetic guide field and the deflection radius ro is shown schematically, which perpendicularly intersects the nominal path plane SE lying in the (x, z) plane.
  • the coils 1, 2, 3, 4 are arranged on both sides of the area Ao so that they do not intersect the area Ao.
  • the winding surfaces of the coils 1, 2, 3, 4 can, as shown here, be aligned parallel or inclined to the surface Ao.
  • Fig. 3 shows a winding of the deflection system, which consists of a double pancake. It is a winding technique that is preferably used in the manufacture of superconducting windings.
  • the winding disc 5 with the smaller radius of curvature r1 ⁇ r0 is produced first and supports the second winding disc 6 with the radius of curvature T2> r1 during winding.
  • the conductor can always be wound under tension. If required, several double pancakes can be connected in series to form a winding package.

Abstract

Système de déflexion magnétique (1-4) pour particules chargées, comportant un agencement de bobines pour générer un champ de guidage magnétique, ledit champ se situant verticalement sur le plan de la trajectoire théorique (SE) et guidant les particules sur une trajectoire de déflexion selon le rayon de déflexion ro. Les bobines produisant le champ de guidage magnétique sont agencées de telle manière que les enroulements ne croisent pas la trajectoire des particules.
