Electron Dynamics in a Wakefield Accelerator Driven by Laser Pulses Carrying Orbital Angular Momentum
Q. Qian, M. Li, Y. Ma +21
Laser pulses carrying orbital angular momentum (OAM) provide a new degree of freedom for controlling plasma-based accelerators. Here, we experimentally demonstrate OAM-driven laser…
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…
