Kinetic modelling of runaway electron avalanches in tokamak plasmas

Runaway electrons can be generated in tokamak plasmas if the accelerating force from the toroidal electric field exceeds the collisional drag force owing to Coulomb collisions with the background plasma. In ITER, disruptions are expected to generate runawa ...

Overview of the FTU results

Basil Duval, Olivier Sauter, Holger Reimerdes, Jonathan Rossel, Alexander Karpushov, Duccio Testa, Lucia Isabel Federspiel, Dávid Wágner, Gabriele Grosso, Doohyun Kim, Cristian Galperti, Donghyun Kim

Since the 2012 IAEA-FEC Conference, FTU operations have been largely devoted to runaway electrons generation and control, to the exploitation of the 140 GHz electron cyclotron (EC) system and to liquid metal limiter elements. Experiments on runaway electro ...

How non-adiabatic passing electron layers of linear microinstabilities affect turbulent transport

Stephan Brunner, Laurent Villard, Julien Stanislas Pierre Dominski

The response of passing electrons in ion temperature gradient and trapped electron mode microturbulence regimes is investigated in tokamak geometry making use of the flux-tube version of the gyrokinetic code GENE. Results are obtained using two different e ...

Kinetic Simulations of the Self-Focusing and Dissipation of Finite-Width Electron Plasma Waves

Stephan Brunner

Two-dimensional simulations, both Vlasov and particle-in-cell, are presented that show the evolution of the field and electron distribution of finite-width, nonlinear electron plasma waves. The intrinsically intertwined effects of self-focusing and dissipa ...

Real-time observation of the charge transfer to solvent dynamics

Majed Chergui, Olivier Christian Bräm, Andrea Cannizzo

Intermolecular electron-transfer reactions have a crucial role in biology, solution chemistry and electrochemistry. The first step of such reactions is the expulsion of the electron to the solvent, whose mechanism is determined by the structure and dynamic ...

Electron beam apparatus

Jean Berney

A method suitable for preparing a specimen for inspection, the method comprising the steps of: irradiating a photocathode so that the photocathode emits electrons from a surface of the photocathode, wherein the emitted electrons each follow a trajectory, a ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...

Inelastic electron tunneling spectroscopy: A route to the identification of the tip-apex structure

Klaus Kern

The vibrational spectrum of a tunneling junction on a clean Cu(111) surface has been characterized by vibrational density of states calculations and inelastic electron tunneling spectroscopy technique. We demonstrate that the achieved spectrum consists not ...

Viability of Dirac phase leptogenesis

Steve Blanchet

We discuss the conditions for a non-vanishing Dirac phase delta and mixing angle theta(13), sources of CP violation in neutrino oscillations, to be uniquely responsible for the observed matter - antimatter asymmetry of the Universe through leptogenesis. We ...
