Psep/PLH control in deuterium and deuterium-tritium JET plasmas

The high confinement mode (H-mode) is a promising route to achieve high performance tokamak operations, as the ones foreseen in ITER and beyond. However, accessing a stable H-mode phase requires that the power across the plasma separatrix, Psep, exceeds a ...

Family of Gaussian wavepacket dynamics methods from the perspective of a nonlinear Schrodinger equation

Jiri Vanicek

Many approximate solutions of the time-dependent Schrodinger equation can be formulated as exact solutions of a nonlinear Schrodinger equation with an effective Hamiltonian operator depending on the state of the system. We show that Heller's thawed Gaussia ...

Stability analysis of alpha driven toroidal Alfven eigenmodes observed in JET deuterium-tritium internal transport barrier plasmas

Paulo Giovane Paschoali Pereira Puglia

A toroidal Alfven eigenmode (TAE) has been observed to be driven by alpha particles in a JET deuterium-tritium internal transport barrier plasma. The observation occurred 50 ms after the removal of neutral beam heating (NBI). The mode is observed on magnet ...
