Oral contribution

In this presentation, I plan to review recent progress of the J-PARC Muon g-2/EDM experiment currently prepared in Japan. This experiment contains novel features of cooling of positive muon down to thermal velocity, three dimensional spiral injection without a horizontal kick, a compact magnetic storage ring. These features might be useful for other applications elsewhere.

Oral contribution

At J-PARC, a muon linac is being developed for future muon $g-2$/EDM experiments. The muon linac starts with an ultra-slow muon (USM) source that generates muons with an extremely small momentum of 3 keV/c (kinetic energy W=25 meV) by laser ionization of thermal muonium. The generated USM accelerated to 5.6 keV by an electrostatic field and injected into a radio frequency quadrupole (RFQ). The...

Precision measurements

Oral contribution

The Fermilab Muon g-2 Experiment aims to search for evidence of new physics by measuring the anomalous magnetic moment of muons, represented by the quantity (g-2)/2. The experiment injects muons into a storage ring, where the precession frequency is measured to determine (g-2)/2.

The analysis of the experiment involves two main components: measuring the difference frequency (ωa) between the...
