First muon acceleration and muon linear accelerator for measuring the muon anomalous magnetic moment and electric dipole moment

Abstract

Muon acceleration using a radio-frequency accelerator was recently demonstrated for the first time. Measurement of the muon anomalous magnetic moment and electric dipole moment at Japan Proton Accelerator Research Complex is the first experiment using accelerated muon beams, and construction will begin soon. The radio-frequency accelerator used in the experiment and the first muon acceleration are described in this paper.

Interdigital H-Mode Drift Tube Linear Accelerator for a Muon Linear Accelerator

“…The basic linac design and numerical beam dynamics calculations have already been completed [10]. In 2017, we demonstrated the first muon acceleration up to 89 keV using a spare RFQ [11]; we have achieved the first milestone in muon linac development.…”

DNN Based Prototype of the Track Reconstruction Algorithm for the MUonE Experiment

“…The experiment dedicated to measure precisely such a hadronic contribution is the MUonE project [21], designed to determine the hadronic part of the running of the electromagnetic coupling constant in the space-like region by the scattering of high-energy muons on atomic electrons in a low-Z target through the elastic process µe → µe [3]. A result with significantly suppressed statistical uncertainty can be achieved on the hadronic contribution to a µ , which, together with the results from running [5] or planned [4] g − 2 experiments supposed to measure directly a µ , would increase the significance of observed discrepancy up to the level of 7 standard deviations.
