Two-Coil Toroid Magnet: An Option of ASTROMAG

摘要

The ASTROMAG particle astrophysics experiment for the space station requires large magnetic field integrals in order to separate high z, high energy isotopes. The two-coil toroid is a magnet configuration which can provide the desired field integral. The two-coil toroid will produce a magnetic field with zero net dipole moment which is required for operation on the space station. Magnetic fields as high as 5 T can be generated within a useful part of the experiment using this configuration. This paper presents a low mass zero mechanical moment two-coil toroid which could be launched by the space shuttle for use on the space station. The magnet design presented in this paper will be cooled using pumped helium II at about 1.8 K. The proposed cryogenic system would operate for up to 2 years on a single load of liquid helium II. The ASTROMAG cryogenic system is designed for helium resupply from the shuttle. (ERA citation 13:012361)
