A method providing the “frozen flux” conditions in a nonsuperconducting coil is suggested and demonstrated with a model. The feasibility of permanent magnet stable levitation in the field of the coil ...with magnetic flux stabilization and mean current control is shown. The method allows researchers to exploit permanent magnet-superconducting body interaction in physical devices, for example, to reproduce, using nonsuperconducting coils, the frozen magnetic flux conditions required for the stable levitation of the magnet over a superconducting body.
GASSOL magnetic gas-filled separator is a new experimental setup being developed at the Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research. It is intended for the effective ...study of chemical properties of short-lived superheavy elements 1. One of the main components of this facility is the superconducting solenoid magnet weighing about 20 ton, designed to create an axially symmetric magnetic field. The paper provides a description of the design, manufacturing technology and assembly of the magnet, as well as the results of mechanical, electromagnetic and thermal calculations to justify its design. The design magnetic field in the aperture of the separator ion chamber with a diameter of 273 mm is 7.6 T.
The Panda experiment is a key experiment at FAIR – European Facility for Antiproton and Ion Research, which is in the development stage in Darmstadt (Germany). The physical program of the experiment ...is focused on the search for exotic particles, research on hadron spectroscopy, the structure of nucleons, nuclear-matter effects, hypernuclei, and in other areas. New experimental forms of matter predicted by theory – glueballs and hybrids – are of great interest. They have not yet been observed. The PANDA facility will be assembled in the storage ring of the HESR antiproton beam. Antiprotons with energy from 1.5 to 15 GeV will be accumulated in the ring. Up to 2·10

opening, are placed inside the lqHe-cryostat. The main features of the design and technique are as follows: a copper stabilizer and soldering technique for the superconducting cable; a stainless steel cryostat; winding technique over a mandrel; coreless type of the coil; low operational current. The details of the PANDA solenoid design including the magnetic field and stress–strain calculations are covered.

A magnet system comprising a 2 T superconducting solenoid for a target spectrometer and a large aperture dipole magnet for a forward spectrometer is being developed for the PANDA experiment at GSI. ...The inner radius of the solenoid coil is 1.1 m. The solenoid is of a split type to provide a warm bore between the coil parts for the target. An energy of 23 MJ is stored in the magnet. The Dipole Magnet will provide a bending momentum of 2 Tmiddotm. The magnet is of the "H-type" with a water-cooled winding. The paper covers magnetic field and forces calculations as well as strength analysis and description of the magnet system components and their implementation

An experimental facility, Probkotron, for determining the correlation coefficients of free-neutron beta -decay has been developed on the basis of a superconducting magnet system. The magnetic field ...distribution meets some special requirements on the magnetic field magnitude, configuration, and homogeneity to provide the conditions for the experiment. To improve the facility duty factor some measures were undertaken during the magnet design development to shorten the field reversal time. Magnet system parameters are presented, and preliminary results of the high field coil test are given.< >
