International audience; The enhancement of power conversion efficiency of a classical axial VIRtual CAthode oscillaTOR (vircator) by introducing one or more reflectors beyond the anode in the cylindrical waveguide is numerically investigated. The tar

International audience; The basic design of an axial virtual cathode oscillator (vircator) with axial extraction operating in TM01 mode is modified by introducing thin conducting disks, also called reflectors, into the cylindrical waveguide. The oper

This paper presents a new approach for ICRH loads used in laboratory testing. Classical “water” loads are convenient but strongly limited in terms of performances. Development of high permittivity loads is under investigation to improve ICRF ante

The coupling between the short scale whistler turbulence and the long scale magnetosonic excitations are studied in both weak and strong turbulence regimes. The coupling occurs via the following mechanism. The nonlinear interactions among the whistle

Transverse focusing or filamentation of weakly nonlinear Alfvén waves propagating in a dispersive medium is studied using an amplitude-equation formalism. Special attention is devoted to the small-β regime, where kinetic effects are weak and Alfvé

A mechanism for small-scale generation in magnetically dominated, homogeneous space plasmas is proposed, resulting from transverse collapse (filamentation) of weakly nonlinear, circularly polarized Alfven waves. It is argued that waves whose frequenc
Numerical evaluation of the role of reflectors to maximize the power efficiency of an axial Vircator

The effects of introducing one or more reflectors inside an axial Vircator are analyzed using CSTParticle Studio® PIC simulation. The power conversion efficiency is shown to be enhanced from 1% to 13% at 3 GHz. The optimum output power is obtained w
