通过加速keV量级缪子实现低发射度缪子束，需要将匹配良好的束流注入加速器，因为束流不匹配会导致发射度增长和加速效率降低。在某一方案中，缪子先被热化至室温，再注入直线加速器。由于能量低、强度弱，非破坏性诊断颇具挑战。我们开发了一套与J-PARC在建加速器兼容的紧凑型低能缪子诊断系统，该系统旨在评估加速前精确调谐所需的束流状态。利用低能缪子源开展的调试显示，该系统具备识别低能缪子信号和测量束流轮廓的能力。
英文摘要
Realization of a low-emittance muon beam through the acceleration of keV-scale muons requires the injection of a suitably matched beam into an accelerator, since beam mismatch can lead to emittance growth and reduced acceleration efficiency. In one such scheme, muons are first thermalized to room temperature and then injected into a linear accelerator. Non-destructive diagnostics are challenging because of the low energy and low intensity. We developed a compact low-energy muon diagnostic system compatible with the accelerator under construction at J-PARC. The system is designed to evaluate beam conditions required for precise tuning prior to acceleration. Commissioning with low-energy muon sources shows the system's capability to identify low-energy muon signals and measure beam profiles.
