Disruption generated secondary runaway electrons in present day tokamaks

Pankratov, I.M.; Jaspers, R. (Вопросы атомной науки и техники, 2000)

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 ...
Distribution functions of secondary runaway electrons

Pankratov, I.M. (Вопросы атомной науки и техники, 2000)

The review of different shapes of runaway electron secondary generation distribution functions are presented. Conditions which lead to different shapes of these functions are considered.
Effect of plasma rotation on the resonance magnetic perturbations at the edge of tokamak plasmas

Pankratov, I.M.; Pavlenko, I.V.; Pomazan, O.A.; Omelchenko, A.Ya. (Вопросы атомной науки и техники, 2012)

In the frame of one-fluid MHD the pressure perturbation resonant excitation by external low frequency helical magnetic perturbations near the plasma edge is investigated. The plasma rotation plays a key role in this ...
Influence of an external low frequency helical perturbation on ballooning modes

Pankratov, I.M.; Omelchenko, A.Ya. (Вопросы атомной науки и техники, 2008)

Equations for investigation of the influence of external helical magnetic perturbations on the ballooning modes are derived in one-fluid MHD with the plasma response and rotation being taken into account.
Modelling of plasma motion response induced by an external rotating helical perturbation in the HYBTOK-II tokamak
