The High Intensity heavy-ion Accelerator Facility (HIAF), scheduled to commence operations in 2026, could deliver muons with energies reaching the GeV scale, offering unique advantages for both applied and fundamental research. In the realm of muon imaging, GeV-energy muons provide significantly higher penetration depth. This enables high-resolution muon tomography of large-scale components...
The large acceptance and high magnetic rigidity of the High Energy Fragment Separator (HFRS) at HIAF provide a promising opportunity to develop a tunable GeV-scale muon beam using a heavy-ion-driven production target. We present a stage-by-stage optimization of the existing HFRS optics using G4beamline simulations and a differential evolution algorithm. The objective function accounts for...
The COMET experiment at J-PARC searches for the charged-lepton-flavour-violating process of coherent muon-to-electron conversion in a muonic atom, $\mu^- N \to e^- N$, with a target single-event sensitivity of $O(10^{-17})$. Its beamline is designed to transport low-energy negative muons produced by a high-intensity proton beam with high efficiency and to maximise the number of stopped muons...
Precision measurements of muon properties and rare decay processes are ideally performed at repetition rates around 50 kHz, yet existing muon facilities are tied to proton accelerators operating in continuous or low repetition rate pulsed modes, making them mismatched to this requirement. We propose an electron driven muon production scheme at the Shanghai High repetition rate XFEL and Extreme...
