The neutrinos from STORed Muons (nuSTORM) facility
The neutrinos from STORed Muons (nuSTORM) facility enables precise neutrino physics studies through the use of innovative neutrino beams created by muon decay, which is characterised by well-defined flavour composition and energy spectra of the neutrino beam. Combined with precise muon flux measurements, with a final target of \%-level precision in neutrino flux determination, this will facilitate a diverse research program probing fundamental neutrino properties.
The facility uses a race-track-like storage ring to store muons with momenta tunable between 1 and 6 GeV/c, enabling precise measurements of $\nu-A$ scattering for both, $\nu_{\mu}$ and $\nu_{e}$ over energy ranges relevant for long-baseline experiments. It also allows for highly sensitive searches for exotic processes and studies of short-baseline flavour transitions exceeding the reach of already planned experiments. As a technology test-bed for high-brightness muon beams, nuSTORM is on the path towards a multi-TeV muon collider and could be part of a test-facility serving a muon-cooling demonstrator.
This talk will present the current status of nuSTORM and its physics capabilities. It will also include results from a FLUKA-based Bayesian optimization study aimed at enhancing the neutrino flux by improving pion capture through optimized target and horn geometries at different pion momentum settings.
