High-temperature Superconducting magnets for use in electron Cyclotron resonance ion sources

Ion sources using electron cyclotron resonance (ECR) require magnets to generate a particular field profile. High temperature superconducting (HTS) magnets offer advantages in power density, efficiency and the overall simplicity of the system. Space Cryomagnetics Ltd of Culham, England, has designed and manufactured HTS magnets for an ion source for Pantechnik in France, and is currently developing a second, more powerful system for the Laboratoire de Physique Subatomique et de Cosmologie (LPSC) in Grenoble, France. This paper describes the design, manufacture and test results of the first of these systems, and the current status of the design and manufacture of the second.
