Time simulation of the nonlinear wave-particle interaction in meters long traveling-wave tubes
Damien F. G. Minenna, Khalil Aliane, Yves Elskens +4
We propose a multi-particle self-consistent Hamiltonian (derived from an N-body description) that is applicable for periodic structures such as traveling-wave tubes (TWTs), gyrotro…
Sticky islands in stochastic webs and anomalous chaotic cross-field particle transport by ExB electron drift instability
D. Mandal, Y. Elskens, X. Leoncini +2
The ExB electron drift instability, present in many plasma devices, is an important agent in cross-field particle transport. In presence of a resulting low frequency electrostatic…
Wave-particle interactions in a long traveling wave tube with upgraded helix
M. C. de Sousa, F. Doveil, Y. Elskens +1
We investigate the interaction of electromagnetic waves and electron beams in a 4 meters long traveling wave tube (TWT). The device is specially designed to simulate beam-plasma ex…
Cross-field chaotic transport of electrons by ExB electron drift instability in Hall thruster
D. Mandal, Y. Elskens, N. Lemoine +1
A model calculation is presented to characterize the anomalous cross-field transport of electrons in a Hall thruster geometry. The anomalous nature of the transport is attributed t…
DIMOHA: A Time-Domain Algorithm for Traveling-Wave Tube Simulations
Damien Minenna, Yves Elskens, Frédéric André +3
To simulate traveling-wave tubes (TWTs) in time domain and more generally the wave-particle interaction in vacuum devices, we developed the DIscrete MOdel with HAmiltonian approach…
Cross-field chaotic transport of electrons by electron drift instability in Hall thrusters
Debraj Mandal, Yves Elskens, Nicolas Lemoine +1
One special interest for the industrial development of Hall thruster is characterizing the anomalous cross-field electron transport observed after the channel exit. Since the ioniz…
Universality of the Abraham-Minkowski dilemma for photon momenta beyond dielectric materials
Damien Minenna, Yves Elskens, Fabrice Doveil +1
The authors) Whenever light is slowed down, for any cause, two different formulas give its momentum. For dielectrics, the coexistence of those momenta was the heart of the century-…
Electromagnetic power and momentum in N-body hamiltonian approach to wave-particle dynamics in a periodic structure
Damien Minenna, Yves Elskens, Frédéric André +1
To model momentum exchange in nonlinear wave-particle interaction, as in amplification devices like traveling-wave tubes, we use an -body self-consistent hamiltonian description…
Low frequency resistive instability in a dusty Hall thruster plasma
Jasvendra Tyagi, Hitendra Malik, Yves Elskens +2
Along with crossed electric and magnetic fields in a Hall thruster, a radial component of electric field is generated that takes ions toward the walls, which causes sputtering and…
