摘要: For ITER-relevant runaway electron studies, such as suppression, mitigation, termination and/or control of a beam, it is important to obtain the electrons after disruption. In this paper we report on first discharges achieved with post-disruptive termed ‘runaway plateau’, in COMPASS tokamak. The plateau produced by massive gas injection argon. Almost all disruptions plateaus occurred during plasma current ramp-up phase. Ar and without were compared for various parameters. Parametrisation shows that fulfil range parameters occurrence. These include density, electric field, disruption speed, effective safety factor, maximum quench field. addition these typical parameters, value just before proved be surprisingly important.
