Magnetic Resonances in ECR-Heated Plasmas of the TJ-II Heliac
Low order rational values of the rotational transform –magnetic resonances, for brevity– can be present inside ECR–heated plasmas of the TJ‐II Heliac, in low magnetic shear conditions, without causing damage to confinement. Moreover, in agreement with previous experience in the TJ‐II, the resonances...

Summary: | Low order rational values of the rotational transform –magnetic resonances, for brevity– can be present inside ECR–heated plasmas of the TJ‐II Heliac, in low magnetic shear conditions, without causing damage to confinement. Moreover, in agreement with previous experience in the TJ‐II, the resonances seem to benefit confinement and are associated to changes in the radial electric field, at least in the density gradient region. These results encourage considering magnetic resonances as possible external actuators on confinement in stellarator/heliotron devices (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
