A paper "Acceleration of Positive Muons by a Radio-Frequency Cavity" was published in Physical Review Letters. This achievement was made possible by the contributions of a team from N-lab and KMI, including Prof. Iijima, Associate Prof. Kenji Inami, Lecturer Kazuhito Suzuki, Mai Yotsuzuka, Kazumichi Sumi, Soh Sugiyama, Yuka Ibaraki, Research Fellow Kazuki Kojima (KMI(now at KEK)), Tadaki Ichikawa, Koichi Ueda, Shota koji, and Ayaka Kondo

In this study, the first-ever acceleration of cooled muons was successfully demonstrated using a Radio-Frequency Quadrupole accelerator, an achievement made possible by combining muon cooling and Radio-Frequency acceleration technologies. This achievement is a major step forward toward the realization of higher-energy muon accelerators and the creation of the exceptionally highly focused muon beams.
