Superconducting Magnets for High Energy
نویسنده
چکیده
Center With the availability of high energy accelerators the need for powerful experimental, beam transport and special magnets is steadily increasing. Experimental high field large volume watercooled or conventional magnets would have power requirements which would be economically unsound. Superconducting magnets have reached a stage where they can be incorporated in connection with high energy physics, and many laboratories are building experimental magnets to be used for charged particle energies between 10 and 20 GeV. Recent developments in hard superconductors, technological improvements and a better understanding of steady state stable behaviour of superconducting magnets enables us to build multimegajoule energy magnets with fields approaching 100 kG in working values of several cubic meters. Recent trends in superconducting magnet design will be discussed. A number of large superconducting magnets currently in operation will be described as well as magnets in stages of procurement and planning. The use of ferromagnetic materials with superconducting magnets, the effects of superfluid and supercritical helium in magnet performance and forced liquid helium cooling will be treated.

Superconducting Accelerator Magnets: a Review of Their Design and Training*
This paper reviews the basic mechanical designs of most of the superconducting magnets developed for high energy hadron accelerators. The training performance of these magnets is compared with an instability factor defined by the square of the current density in the stabilizing copper divided by the surface-to-volume ratio of the strands. A good correlation is observed.

In the LHC about 6500 superconducting corrector magnets will be powered either in stand-alone mode or in electrical circuits of up to 154 magnets. Single corrector magnets are designed to be self-protected in case of a quench. The protection scheme of magnets powered in series depends on the energy stored in the magnet and on the number of magnets in the circuit. A quench is detected by measuri...
متن کاملDevelopment of a compact superconducting rotating-gantry for heavy-ion therapy
An isocentric superconducting rotating-gantry for heavy-ion therapy is being developed [1]. This rotating gantry can transport heavy ions having 430 MeV/u to an isocenter with irradiation angles of over ±180°, and is further capable of performing fast raster-scanning irradiation [2]. A layout of the beam-transport line for the compact rotating-gantry is presented in Fig. 1. The rotating gantry ...
