Laser and beam driven wakefields promise orders of magnitude increases in electric field gradients for particle accelerators for future applications. Key areas to explore include the emittance properties of the generated beams and overcoming the deph

The generation of low emittance electron beams from laser-driven wakefields is crucial for the development of compact X-ray sources. Here, we show new results for the injection and acceleration of quasi-monoenergetic electron beams in low amplitude w

Measuring the orbital angular momentum of high-power laser pulses

Autor: A. F. Savin, Robert Bingham, Christopher Spindloe, M. W. Mayr, Peter Norreys, Kevin Glize, B. Spiers, Ramy Aboushelbaya, Nicolas Bourgeois, R. H. W. Wang

In this article, we showcase the experimental results of methods to produce and characterize orbital angular momentum (OAM) carrying high-power lasers. The OAM pulses were produced on the ASTRA laser of the Central Laser Facility using a continuous s

Publikováno v: Physical Review E

Inertial confinement fusion fuel suffers increased x-ray radiation losses when carbon from the capsule ablator mixes into the hot-spot. Here, we present one- and two-dimensional ion Vlasov-Fokker-Planck simulations that resolve hot-spot self-heating
