The non-axisymmetric magnetic field, naturally present in every tokamak, constraints the machine operational space. A set of dedicated 'Error Field Correction Coils' (EFCC) is proposed for JET, which will replace the unreliable existing 'saddle coils'. The new coils are specified to compensate the main harmonic contribution to error field induced modes. The EFCC structural design comprises a cable coil wound in a metallic casing supported on the JET iron magnetic circuit. Existing power supplies will drive the coils. The EFCC are expected to be installed in 2001 JET shutdown. © 2001 UKAEA. Published by Elsevier Science Ltd. All rights reserved.
