Disruption generated secondary runaway electrons in present day tokamaks

Abstract

An analysis of the runaway electron secondary generation during disruptions in present day tokamaks (JET, JT- 60U, TEXTOR) was made. It was shown that even for tokamaks with the plasma current I ~ 100 kA the secondary generation may dominate the runaway production during disruptions. In the same time in tokamaks with I ~ 1 MA the runaway electron secondary generation during disruptions may be suppressed.
