Description
We are developing a device to trap muons in a Penning trap at J-PARC. Recently, we succeeded in trapping negative muons in vacuum using a pulsed electric field and a static magnetic field. Although a negative muon stopped in matter is captured by its atomic nucleus and its lifetime gets shorter than in vacuum, we can measure the lifetime of the negative muon directly using our muon trap technique. In addition, we aim to observe anti-muonium for the first time by trapping negative muons and positrons simultaneously, which will lead to precision spectroscopy measurements of anti-muonium and CPT tests in the muon sector by comparing basic parameters (mass, lifetime, energy levels, etc.) of the positive and negative muons. This poster will report on the latest results and status of our muon Penning trap project.
