Efficient generation of new orbital angular momentum beams by backward and forward stimulated Raman scattering
Q. S. Feng, R. Aboushelbaya, M. W. Mayr +9
Laser beams carrying orbital angular momentum (OAM) provide an additional degree of freedom and have found wide applications ranging from optical communications and optical manipul…
Enabling the Realisation of Proton Tomography
Ben T. Spiers, Ramy Aboushelbaya, Qingsong Feng +6
The proton radiography diagnostic is widely used in laser-plasma experiments to make magnetic field measurements. Recent developments in analysis have enabled quantitative reconstr…
Methods for Extremely Sparse-Angle Proton Tomography
Ben T. Spiers, Ramy Aboushelbaya, Qingsong Feng +6
Proton radiography is a widely-fielded diagnostic used to measure magnetic structures in plasma. The deflection of protons with multi-MeV kinetic energy by the magnetic fields is u…
Nonlinear wakefields and electron injection in cluster plasma
Marko Mayr, Ben Spiers, Ramy Aboushelbaya +6
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 t…
Kinetic simulations of fusion ignition with hot-spot ablator mix
James D. Sadler, Yingchao Lu, Benjamin Spiers +9
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…
Energy absorption in the laser-QED regime
Alex F Savin, Aimee J Ross, Ramy Aboushelbaya +4
A theoretical and numerical investigation of non-ponderomotive absorption at laser intensities relevant to quantum electrodynamics is presented. It is predicted that there is a reg…
