Terahertz pulse generation from relativistic laser wakes in axially magnetized plasmas

Autor: C. Tailliez, X. Davoine, L. Gremillet, L. Bergé

Publikováno v: Physical Review Research, Vol 5, Iss 2, p 023143 (2023)

Using multidimensional particle-in-cell simulations, we demonstrate the generation of >30GVm^{−1} terahertz (THz) fields by relativistic, few-femtosecond laser pulses interacting with gas plasmas embedded in >100T magnetic fields parallel to the la

Laser-driven neutron sources could offer a promising alternative to those based on conventional accelerator technologies in delivering compact beams of high brightness and short duration. We examine this through particle-in-cell and Monte Carlo simul

Characterization and performance of the Apollon short-focal-area facility following its commissioning at 1 PW level

Publikováno v: Matter and Radiation at Extremes, Vol 6, Iss 6, Pp 064402-064402-14 (2021)

We present the results of the first commissioning phase of the short-focal-length area of the Apollon laser facility (located in Saclay, France), which was performed with the first available laser beam (F2), scaled to a nominal power of 1 PW. Under t

Spatiotemporal dynamics of ultrarelativistic beam-plasma instabilities

Publikováno v: Physical Review Research, Vol 4, Iss 2, p 023085 (2022)

An electron or electron-positron beam streaming through a plasma is notoriously prone to microinstabilities. For a dilute ultrarelativistic infinite beam, the dominant instability is a mixed mode between longitudinal two-stream and transverse filamen

Probing ultrafast magnetic-field generation by current filamentation instability in femtosecond relativistic laser-matter interactions

Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023123 (2020)

The current filamentation instability is a key phenomenon underpinning various processes in astrophysics, laboratory laser-plasma, and beam-plasma experiments. Here we show that the ultrafast dynamics of this instability can be explored in the contex

Numerical investigation of spallation neutrons generated from petawatt-scale laserdriven proton beams

Publikováno v: Matter and Radiation at Extremes
Matter and Radiation at Extremes, 2022, 7, pp.024401. ⟨10.1063/5.0060582⟩

Due to their high cost of acquisition and operation, there are still a limited number of high-yield, high-flux neutron source facilities worldwide. In this context, laser-driven neutron sources offer a promising, cheaper alternative to those based on
