Research progress on advanced positron acceleration

Abstract

Plasma Wakefield Acceleration (PWFA) is a highly promising method that can reduce the scale and cost of future electron–positron collider experiments. While significant breakthroughs have been achieved in electron acceleration both theoretically and experimentally, generating high-quality positron beams in plasma presents greater challenges. This paper reviews advanced positron acceleration schemes, including particle beam-driven wakefield acceleration, laser-driven wakefield acceleration, radiation acceleration, and hollow plasma channel acceleration. The hollow plasma channel scheme is a promising method that can provide stable and efficient acceleration of positrons, making it more advantageous for experimental implementation.
