The physical principals are pretty sound. We do already generate neutrino beams, like at Fermilab[2]. And we do have the ability to detect neutrinos in water, optically as ANTARES[3] does, or acoustically, as SAUND[4] demonstrated. There are some serious engineering challenges to building a muon storage ring, which is why we don&#x27;t have any. If we could build them, we could build…</p><p><a href="https://hackerpaper.kaipfister.de/p/0909.4554/">Paper and discussion history</a>. A mention is not an endorsement.</p>hep-ph
