μ子加速是探索物理学新前沿的一项重要技术。计划在J-PARC中使用μ子线性加速器进行μ子偶极矩的新测量。利用薄金属箔靶和束流诊断系统研制了世界上第一个μ子加速器的低能μ子源。成功地观察到了来自薄金属箔靶的负μ 鎓离子作为LE μ子源。同时，利用LE专用束流剖面监测仪测量了LE正μ子的束流剖面。使用射频四极直线加速器（Radio-Frequency Quadrupole Linac）的μ子加速测试正在准备作为μ子加速器开发的第一步。本文介绍了第一次μ子加速实验的最新情况。
Muon acceleration is an important technique in exploring the new frontier of physics. A new measurement of the muon dipole moments is planned in J-PARC using the muon linear accelerator. The low-energy (LE) muon source using the thin metal foil target and beam diagnostic system were developed for the world's first muon acceleration. Negative muonium ions from the thin metal foil target as the LE muon source was successfully observed. Also the beam profile of the LE positive muon was measured by the LE-dedicated beam profile monitor. The muon acceleration test using a Radio-Frequency Quadrupole linac (RFQ) is being prepared as the first step of the muon accelerator development. In this paper, the latest status of the first muon acceleration test is described.
