Description	Extensive analysis of disruptions in JET has helped advance the understanding of trends of disruption-generated runaway electrons. Tomographic reconstruction of the soft x-ray emission has made possible a detailed observation of the magnetic flux geometry evolution during disruptions. With the aid of soft and hard x-ray diagnostics runaway electrons have been detected at the very beginning of disruptions. A study of runaway electron parameters has shown that an approximate upper bound for the conversion efficiency of pre-disruptive plasma currents into runaways is about 60% over a wide range of plasma currents in JET. Runaway generation has been simulated with a test particle model in order to verify the results of experimental data analysis and to obtain the background for extrapolation of the existing results onto larger devices such as ITER.

(en) Pomocí studia disrupcí na tokamaku JET se daří zlepšovat chápání vlastostí ubíhajících elektronů, které vznikají během disrupce. Experimentální data pocházejí především z měření měkého a tvrdého rentgenového záření, tomografie umožnila sledovat i prostorový výskyt ubíhajících elektronů. Počítačová simulace procesů se dobře shoduje s naměřenými daty za předpokladu, že elektronová teplota je 10eV. Studie je velmi důležitá pro projekt ITER, který zřejmě bude potřebovat systém na utlumení disrupcí. (cs)
