Enhanced confinement with increased extent of the low magnetic shear region in tokamak plasma
Lorenzo Nasi, Marie-Christine Firpo
The Hamiltonian representation of magnetic field lines enables one to study their confinement properties in tokamaks through the use of symplectic maps such as the symmetric tokama…
Early out-of-equilibrium beam-plasma evolution
M. -C. Firpo, A. F. Lifschitz, E. Lefebvre +1
We solve analytically the out-of-equilibrium initial stage that follows the injection of a radially finite electron beam into a plasma at rest and test it against particle-in-cell…
Early nonlinear regime of MHD internal modes: the resistive case
M. -C. Firpo
It is shown that the critical layer analysis, involved in the linear theory of internal modes, can be extended continuously into the early nonlinear regime. For the m=1 resistive m…
Characterization of the initial filamentation of a relativistic electron beam passing through a plasma
A. Bret, M. -C. Firpo, C. Deutsch
The linear instability that induces a relativistic electron beam passing through a return plasma current to filament transversely is often related to some filamentation mode with w…
Dynamical analysis of the nonlinear growth of the m=n=1 resistive internal mode
Marie-Christine Firpo, Bruno Coppi
A dynamical analysis is presented that self-consistently takes into account the motion of the critical layer, in which the magnetic field reconnects, to describe how the m=n=1 resi…
