Laser-plasma interactions with a Fourier-Bessel Particle-in-Cell method
Igor A. Andriyash, Remi Lehe, Agustin Lifschitz
A new spectral particle-in-cell (PIC) method for plasma modeling is presented and discussed. In the proposed scheme, the Fourier-Bessel transform is used to translate the Maxwell e…
Energy boost in laser wakefield accelerators using sharp density transitions
A. Döpp, E. Guillaume, C. Thaury +3
The energy gain in laser wakefield accelerators is limited by dephasing between the driving laser pulse and the highly relativistic electrons in its wake. Since this phase depends…
Resonance-induced enhancement of the energy harvesting performance of piezoelectric flags
Yifan Xia, Sebastien Michelin, Olivier Doare
The spontaneous flapping of a flag can be used to produce electrical energy from a fluid flow when coupled to a generator. In this paper, the energy harvesting performance of a fla…
Weak Dirichlet processes with jumps
Elena Bandini, Francesco Russo
This paper develops systematically the stochastic calculus via regularization in the case of jump processes. In particular one continues the analysis of real-valued càdlàg weak Dir…
Special weak Dirichlet processes and BSDEs driven by a random measure
Elena Bandini, Francesco Russo
This paper considers a forward BSDE driven by a random measure, when the underlying forward process X is special semimartingale, or even more generally, a special weak Dirichlet pr…
9 GeV Energy Gain in a Beam-Driven Plasma Wakefield Accelerator
M Litos, E Adli, J M Allen +15
An electron beam has gained a maximum energy of 9 GeV per particle in a 1.3 m-long electron beam-driven plasma wakefield accelerator. The amount of charge accelerated in the spectr…
