Dear NuFACT'00 Participant:

On behalf of the organizing committee for NuFACT'00, we call your attention to the Second International Workshop on Neutrino Factories based on Muon Storage Rings (NuFACT'00). The Workshop will be held at the Naval Postgraduate School in Monterey, CA, May 22-26, 2000. Results from Super-K provide strong evidence for the existence of neutrino oscillations. These results, together with the increased confidence in our ability to produce and manipulate intense muon beams (arising from the work of the newly renamed Neutrino Factory and Muon Collider Collaboration, and from Neutrino Factory groups at CERN, KEK and elsewhere), motivated the first Workshop, NuFACT'99, held last July in Lyon, France. NuFACT'99 generated considerable enthusiasm about the physics potential of a neutrino factory, and the realization that, while there are significant R&D challenges, a muon storage ring is much simpler than a muon collider.

A muon storage ring, as presently envisioned, would have energy in the 10-50 GeV range, and produce directed beam(s) of intense neutrinos, with about 10²⁰ -10²¹ stored muons decaying per year. Ideally, the geometry of the "ring" should be able to provide neutrinos to both near and distant (transcontinental) experimental facilities. The generation of the muon beam requires a powerful proton source (1-4 MW), muon capture and subsequent manipulation, cooling, acceleration, and storage of these muons. Over the last few months, both CERN and FNAL have initiated studies of the required R&D, feasibility, costs, and physics potential of neutrino factories. Some of these studies are to be completed in the Spring 2000. It is therefore quite timely to have NuFACT'00 this May. It will be devoted to the physics (particle physics, detector physics, machine physics) of neutrino sources based on muon storage rings.
