Mirnov oscillations

Mirnov oscillations (a.k.a. magnetic oscillations) are amplitude perturbations of the magnetic field in a plasma. It is named after Sergei V. Mirnov who designed a probe to measure these oscillations in 1965.[1] The probe name is Mirnov coil.

Mirnov oscillations have been extensively studied in tokamaks[2][3][4][5] as they provide information about the plasma instabilities that occur within the system.[6][7][8] The instabilities create local fluctuations in the current which induce a varying magnetic flux density, and are picked up by the coils due to Faraday's law of induction.
