Gamma radiation vortex burst in the nonlinear Thomson scattering with refocusing spiral plasma mirror - EurekAlert
The high energy radiation that carry the orbit angular momentum has become an extremely important tool to investigate the angular momentum related physics in microworld. But the generation and characterization of high energy radiation vortex remain the urgent issues to be solved. To address this issue, the group of Profs.Liming Chen and Wenchao Yan from the Key Laboratory for Laser Plasmas of Shanghai Jiao Tong University came up with the configuration by using the special refocusing spiral plasma mirror to combine the laser wakefield acceleration with the nonlinear Thomson scattering.
