The high-frequency 𝐵ᵣ have short radial and poloidal correlation lengths L < 5, in contrast with the usual Mirnov oscillations with 𝑓≈7 kHz and 𝐿≫5 cm. The observed magnitude 𝛴⁢|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.5 pagesen-US©2025 American Physical SocietyMagnetic pickup loopsMacrotor tokamakbroad spectrum of oscillationUMBC Optical Fiber Communications LaboratoryUMBC High Performance Computing Facility (HPCF)short radial and poloidal correlation lengthsradial magnetic perturbationsText
