Collimated gamma-ray beams from structured laser-irradiated targets -- how to increase the efficiency without increasing the laser intensity
O. Jansen, T. Wang, Z. Gong +5
Using three-dimensional kinetic simulations, we examine the emission of collimated gamma-ray beams from structured laser-irradiated targets with a pre-filled cylindrical channel. T…
Leveraging extreme laser-driven magnetic fields for gamma-ray generation and pair production
Oliver Jansen, Tao Wang, David Stark +2
The ability of an intense laser pulse to propagate in a classically over-critical plasma through the phenomenon of relativistic transparency is shown to facilitate the generation o…
Tree Code for Collision Detection of Large Numbers of Particles Application for the Breit-Wheeler Process
Oliver Jansen, Emmanuel d'Humières, Xavier Ribeyre +2
Collision detection of a large number N of particles can be challenging. Directly testing N particles for collision among each other leads to N 2 queries. Especially in scenarios,…
Pair creation in collision of --ray beams produced with high intensity lasers
X. Ribeyre, M. Lobet, E. D'Humières +3
Direct production of electron--positron pairs in two photon collisions, the Breit--Wheeler process, is one of the basic processes in the Universe. However, it has never been observ…
Characterization and Application of Hard X-Ray Betatron Radiation Generated by Relativistic Electrons from a Laser-Wakefield Accelerator
Michael Schnell, Alexander Sävert, Ingo Uschmann +3
The necessity for compact table-top x-ray sources with higher brightness, shorter wavelength and shorter pulse duration has led to the development of complementary sources based on…
Field-reversed bubble in deep plasma channels for high quality electron acceleration
A. Pukhov, O. Jansen, T. Tueckmantel +2
We study hollow plasma channels with smooth boundaries for laser-driven electron acceleration in the bubble regime. Contrary to the uniform plasma case, the laser forms no optical…
