AI 中文摘要
缪子加速是产生宽能量范围内低发射度缪子束的关键技术，已提出多种加速方案，应用范围涵盖低能μSR、精确粒子物理测量、中微子工厂及缪子对撞机。然而，缪子加速的实验演示迄今有限。在J-PARC，正缪子加速器基于超慢缪子的产生与加速开发，2024年已实现正缪子的首次射频（RF）加速演示。本综述先概述缪子加速方法及相关实验，再介绍J-PARC的加速方法、当前进展及未来展望。
英文摘要
Muon acceleration is a key technology for producing low-emittance muon beams over a wide energy range. Various acceleration schemes have been proposed for applications ranging from low-energy $μ$SR and precision particle-physics measurements to neutrino factories and muon colliders. Experimental demonstrations of muon acceleration, however, have so far been limited. At J-PARC, a positive-muon accelerator based on the production and acceleration of ultraslow muons is being developed, and in 2024 the first RF acceleration of positive muons was demonstrated. In this review, we provide a brief overview of muon-acceleration methods and related experiments, and then review the acceleration method, current status, and future prospects at J-PARC.
