摘要：
当前，迫切需要一种针对反物质粒子的超高加速梯度方法，这对探索物质起源、CP 破坏、天体物理学和医学物理学具有重要意义。传统的激光驱动电荷分离场加速器加速梯度低且正电子加速区域有限，相比之下，我们提出了一种具有实现优势的创新性高梯度正电子加速机制。将相对论电子束注入稠密等离子体微管中，可产生稳定且周期性高强度中红外辐射（mid-IR）场，其场强达数十 GV/m。该场与电子束同步传播，在 140 皮秒内使正电子束获得 1 GeV 的能量增益，且在稳定相位期间能量散布极小，约为 1.56%。通过利用连续的中红外辐射，电子束向单个正电子束或同时向三个正电子束传递能量的效率可分别高达 20% 和 40%。该加速方案能够以连续、稳定且高效的方式，实现单个正电子束的级联加速以及多个正电子束的串行加速。
英文摘要：
Nowadays, there is a desperate need for an ultra-acceleration-gradient method for antimatter particles, which holds great significance in exploring the origin of matter, CP violation, astrophysics, and medical physics. Compared to traditional accelerators with low gradients and a limited acceleration region for positrons in laser-driven charge separation fields, we propose an innovative high-gradient positron acceleration mechanism with implementation advantages. Injecting a relativistic electron beam into a dense plasma micro-tube generates a stable and periodic high-intensity mid-infrared radiation (mid-IR) field, reaching tens of GV/m. This field, propagating synchronously with the electron beam, achieves a 1 GeV energy gain for the positron bunch within 140 picoseconds with a minimal energy spread-approximately 1.56% during a stable phase. By utilizing continuous mid-IR, the efficiency of energy transfer from the electron beam to either a single positron bunch or three positron bunches simultaneously could reach up to 20% and 40%, respectively. This acceleration scheme can achieve cascaded acceleration for a single positron bunch and series acceleration for multiple positron bunches in a continuous, stable, and efficient manner.
