The J-PARC muon g-2/EDM experiment aims to measure the muon magnetic moment anomaly (a_μ = (g-2)/2) and to search for the muon electric dipole moment (EDM), with sensitivity comparable to the highest in the world. This will be achieved using a small-emittance muon beam, created by cooling muons to thermal energy at room temperature and accelerating them with a four-stage linac. The small...
A multi-TeV Muon Collider (MuC) has the unique potential to provide both precision measurements and the highest energy reach in one machine that cannot be paralleled by any currently available technology. One of the key challenges in development of the MuC is delivery of a high brightness muon beam, which is essential to produce sufficient luminosity. Ionization cooling, is currently the only...
The High Intensity heavy-ion Accelerator Facility (HIAF) is a mega-scientific facility in China. A magnetized electron cooling system is used in the Spectrometer Ring (SRing) to improve the beam quality for internal target experiments. The maximum electron beam energy is up to 450 keV. In 2025, all components of the cooler have been installed in the SRing tunnel. In this report, the...
