Therefore, behaviour ofrunaway electron (RE) beams has been studied at the COMPASS tokamak in the frame of dedicated experiments focused on their generation and subsequent mitigation, mainlyusing massive gas injection. In this contribution, we introduce fast observations of the generated RE beams done by different types of high-speed cameras, AXUV detectors as aproxy of fast bolometers, ECE and hard X-ray and photo-neutron detectors. Time dependence and spatial localization of RE have been investigated with respect to severalaspects: formation of the beam, with a special attention to observed filamentary and quiet phases of the beam existence, interaction of the beam with the background plasma as well aswith the tokamak control system, beam extinction by slow decay or by sudden termination.
