On 20th January 2016, the first high-speed colour videos from the COMPASS tokamak discharges were recorded by a new fast CMOS camera of the Photron Mini UX100 type. In ohmically heated plasmas in a divertor configuration and deuterium as a working gas, the videos of 1 000-20 000 frames per second revealed formation of the plasma column, its shaping and refilling by the gas puffing, and also a plasma-wall interaction resulting in dust particles propagating across the vacuum vessel of the tokamak.
Dne 20. ledna 2016 byla prostřednictvím nové rychlé CMOS kamery typu Photron Mini UX100 zaznamenána první barevná videa výbojů tokamaku COMPASS. V ohmicky ohřívaných plazmatech s divertorovou konfigurací a deuterium jakožto pracovním plynem, ukázala videa o 1 000-20 000 snímcích za sekundu formování sloupce plazmatu, jeho tvarování a doplňování pracovního plynu a také interakci plazmatu se stěnou vedoucí k vytváření prachových částic letících napříč vakuovou komorou tokamaku.
