Open AccessThe emission of γ-Ray beams with orbital angular momentum in laser-driven micro-channel plasma target
We investigated the emission of multi-MeV γ-Ray beams with orbital angular momentum (OAM) from the interaction of an intense circularly polarized (CP) laser with a micro-channel plasma target. The driving lase...

Open AccessQuantum reflection above the classical radiation-reaction barrier in the quantum electro-dynamics regime
High brightness gamma rays can be generated by colliding an ultra-intense laser pulse with a high energy electron beam. This collision phenomenon also represents a powerful approach to explore new physics in t...
