摘要：
Magnetic pickup loops inserted into the Macrotor tokamak have shown a broad spectrum of oscillation in Br and Bp up to f100 kHz. The high-frequency Br have short radial and poloidal correlation lengths L<5 cm, in contrast with the usual Mirnov oscillations with f7 kHz and L5 cm. The observed magnitude |Br|BT>10-5, where the summation extends over all f>30 kHz, is in the range in which such radial magnetic perturbations may be contributing to anomalous electron energy transport. © 1979 The American Physical Society.
