摘要：

我们提出利用慢速μ子装置并结合回旋辐射探测，对μ子衰变中的弱相互作用进行精密检验。首先将慢速正μ子束团注入一个圆柱形超导真空室，该真空室具有均匀的强轴向磁场，以在径向上约束μ子。μ子衰变产生的正电子可通过其回旋辐射进行探测，该辐射能够通过与真空室耦合的波导传输到低噪声电子设备。衰变正电子的能量在低能区可被精确测量至eV量级，这对马约拉纳中微子和弱相互作用新结构等新物理效应十分敏感。

英文摘要：

We propose to use slow muons facilities combined with cyclotron radiation detection for precision test of the weak interaction in the muon decays. Slow positive muon bunches are first injected into a cylindrical superconducting vacuum chamber with uniform strong axial magnetic fields to radially confine the muons. The positrons resulting from muon decays can be detected by their cyclotron radiation, which can be transported to low-noise electronic devices through waveguides coupled to the chamber. The decay positron's energy can be precisely measured down to eV level in the low energy region, which is sensitive to new physics effects such as Majorana neutrinos and new structures of weak interactions.
