High-flux positron generation via the ultra-intense laser irradiating density-modulated plasmas
To investigate plasma density during the Breit–Wheeler positron generation, a comparative study of four plasma targets is performed via the PIC (particle-in-cell) code EPOCH. When an ultra-intense laser (2.8×1023 Wcm−2) is incident, more positrons with high energy are generated in the increasing den...
