Abstract

A new scheme is proposed in which high-flux and high-density positrons are generated via ultra-intense laser pulses colliding in a cylinder filled with near-critical-density plasmas. Comparing with the only cylinder case and the only gas case, positron generation is enhanced with a higher density. When discussing the influence of plasma density in positron generation, an optimal gas density is found around the near-critical density. The scheme will facilitate the realization of positron generation in labs and further applications of positrons.
