Error field correction coils on JET EFCCs are four square

shaped coils (~ 6m x 6m) positioned outside of JET vessel ICoil ≤ 3 kA x 16 turns

Original purpose of these coils is to compensate n=1 intrinsic error field

Depending on the relative phasing of the currents in individual coils, either n=1 or n=2 fields can be generated Y. Liang, 34th EPS, Warsaw
