Behavior of the fast neutrals generated during a disruption in the T-11M tokamak

Results are presented from experimental studies of the generation of high-energy neutrals during a major disruption in the T-11M tokamak. Fast-neutral fluxes from the plasma, magnetic perturbations, and the neutral-hydrogen and impurity radiation from the plasma core are measured simultaneously in the course of disruption. A high (～1 μs) temporal resolution of the recording system (the characteristic disruption time being about 100 μs) makes it possible to thoroughly investigate the time behavior of the processes that occur during a disruption.
