Mirnov oscillations

mirnov oscillations

(Science: physics) fluctuations in the poloidal magnetic field (of a toroidal magnetic confinement system) which rotate in the electron diamagnetic drift direction at a speed comparable to the electron diagmagnetic drift velocity and with frequencies due to 5-20 kHz. Mirnov oscillations arise from tearing modes. Poloidal magnetic probes used to measure the poloidal field in order to diagnose Mirnov oscillations (and other magnetohydrodynamic phenomena) are often called Mirnov coils or Mirnov loops.
