Global linear stability analysis of kinetic Trapped Ion Mode (TIM) turbulence in tokamak plasma using spectral method
D. Mandal, M. Lesur, E. Gravier +4
Trapped ion modes (TIM) belong to the family of ion temperature gradient (ITG) modes, which are one of the important ingredients in heat turbulent transport at the ion scale in tok…
Sticky islands in stochastic webs and anomalous chaotic cross-field particle transport by ExB electron drift instability
D. Mandal, Y. Elskens, X. Leoncini +2
The ExB electron drift instability, present in many plasma devices, is an important agent in cross-field particle transport. In presence of a resulting low frequency electrostatic…
Ultra slow electron holes in collisionless plasmas: stability at high ion temperature
D. Mandal, D. Sharma, H. Schamel
Numerical simulations recover ultra slow electron holes (EH) of electron-acoustic genre propagating stably well below the ion acoustic speed where the ion response disallows any kn…
Cross-field chaotic transport of electrons by ExB electron drift instability in Hall thruster
D. Mandal, Y. Elskens, N. Lemoine +1
A model calculation is presented to characterize the anomalous cross-field transport of electrons in a Hall thruster geometry. The anomalous nature of the transport is attributed t…
Cross-field chaotic transport of electrons by electron drift instability in Hall thrusters
Debraj Mandal, Yves Elskens, Nicolas Lemoine +1
One special interest for the industrial development of Hall thruster is characterizing the anomalous cross-field electron transport observed after the channel exit. Since the ioniz…
Electron hole instability in linearly sub-critical plasmas
Debraj Mandal, Devendra Sharma, Hans Schamel
Electron holes (EH) are highly stable non-linear structures met omnipresently in driven collision-less hot plasmas. A mechanism destabilizing small perturbations into holes is esse…
