Observation of geodesic acoustic mode-like oscillations on COMPASS
Original language description
We present observation of plasma potential oscillations on the COMPASS tokamak detected in a form of long range correlations between pair of reciprocating probes. The oscillations exhibit several characteristic features of geodesic acoustic mode (GAM). The probe diagnostics were supplemented by magnetic pick-up coils with full poloidal coverage at several toroidal locations and toroidal and poloidal structure of oscillations of magnetic field associated with the mode are discussed. Moreover, change of frequency and amplitude of the oscillations is observed during sawtooth crashe cycle and during penetration of externally applied magnetic perturbations into the plasma.
