Overview on recent progress in magnetron injection gun theory and design for high power gyrotrons

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Trach-Minh Tran, Ioannis Pagonakis, Jérémy Genoud, François Jean Gaston Legrand

The magnetron injection gun (MIG) is one of the most critical subcomponents in gyrotrons. The electron beam, which has the primary role on the gyrotron operation, is generated and configured at this part of the tube. The electron beam properties determine ...

TWANG-PIC, a novel gyro-averaged one-dimensional particle-in-cell code for interpretation of gyrotron experiments

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Jérémy Genoud, Trach-Minh Tran

A new gyrotron simulation code for simulating the beam-wave interaction using a monomode time-dependent self-consistent model is presented. The new code TWANG-PIC is derived from the trajectory-based code TWANG by describing the electron motion in a gyro-a ...

Bootstrap current calculations with the SPBSC and the VENUS delta f codes for the Large Helical Device

Olivier Sauter, Wilfred Anthony Cooper, Trach-Minh Tran

Total bootstrap current calculations with the updated VENUS+δf code that incorporates energy convolution and the momentum correction technique have been performed for the reference tokamak JT-60U cases and for the experimental Large Helical Device (LH ...

Linear and non-linear studies of spurious backward-wave instabilities in a smooth-wall gyrotron beam duct

Patryk Kaminski, Stefano Alberti, Trach-Minh Tran, Jérémy Genoud

Recently developed self-consistent models for beam-wave interaction simulations of a gyrotron oscillator are used to study spurious backward-wave instabilities in smooth-wall metallic beam ducts. Starting from a simple case with a basic geometry, the influ ...

Nonlinear low noise particle-in-cell simulations of electron temperature gradient driven turbulence

Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan

In this Letter, it is shown that global, nonlinear, particle-in-cell (PIC) simulations of electron temperature driven turbulence recover the same level of transport as flux-tube codes when the level of statistical noise, associated with the PIC discretizat ...

Moment approach to the bootstrap current in nonaxisymmetric toroidal plasmas using deltaf Monte Carlo methods

Wilfred Anthony Cooper, Trach-Minh Tran

To evaluate the bootstrap current in nonaxisymmetric toroidal plasmas quantitatively, a deltaf Monte Carlo method is incorporated into the moment approach. From the drift-kinetic equation with the pitch-angle scattering collision operator, the bootstrap cu ...
