Behaviour of disruption generated runaways in JET

摘要

Expeiments have established the regions of parameter space in JET that lead to runaway generation in disruptions. Previous measurements on the structure of the runaway beam have been confirmed. The delay in runaway generation Following temperature collapse is found to be caused by the very high density generated by the disruption. It is Shown that runaway generation in JET can be best modelled and understood by including avalanche processes.
