本文报道了在日本理研—RAL介子装置上建造慢介子束流线的最新进展。慢介子是由热速度的介子再加速而来的介子。与传统的介子束相比，这种光束预计具有非常小的发射率，在传统的介子束中，介子是从静止或运动的介子衰变中获得的。特别是它的能量扩散小，使得μSR技术可以应用于薄膜、多层体系、纳米材料和其他有限维物体的研究。在未来的中微子工厂中可以实现的强慢μ子束将是材料科学的宝贵工具。
We report recent progress of slow muon beam line constructed at the RIKEN‐RAL muon facility. The slow muons are muons which are re‐accelerated from the one at thermal velocity. This beam is expected to have very small emittance compared with conventional muon beam, where muons are obtained from decays of pions at rest or on move. Especially, its smallness of energy spread will make it possible to apply μSR technique to the studies of thin films, multilayered systems, nanomaterials, and other objects of restricted dimensionality. Intense slow muon beams which can be realized at future neutrino factories will be a valuable tool for material science.
