The work proved capability of the camera to detect several types of oscillatory modesin the COMPASS plasma in the frequency range 500 Hz – 50 kHz, such as sawteeth (~400 Hz), tearing mode (~10 kHz) or geodesicacoustic mode (~30 kHz). Moreover, method for visualising their spatial structure has been proposed and tested on the case of arotating ~10 kHz tearing mode. In addition, the camera has been used as a tool to study time evolution of divertor strike pointsplitting induced by resonant magnetic perturbations.
