nuSTORM: Neutrinos from Stored Muons

A.D. Bross
Fermilab, Batavia, USA

Neutrino beams produced from the decay of muons in a racetrack-like decay ring provide a powerful way to study short-baseline neutrino oscillation and neutrino interaction physics. In this talk, I will describe the facility, nuSTORM, and show how the unique neutrino beam at the facility will enable experiments of unprecedented precision to be carried out. I will present sensitivity plots that indicated that this approach can provide well over 5 σ confirmation or rejection of the LSND/MinBooNE results and can be used to perform neutrino interaction measurements of unprecedented precision. The unique ν beam available at the nuSTORM facility has the potential to be transformational in our approach to ν interaction physics, offering a “ν light source” to physicists from a number of disciplines. Finally, the nuSTORM facility can also provide intense short-pulsed beams of low energy muons suitable for future 6D muon ionization cooling experiments. This can be simultaneously while carrying out the neutrino program.

A facility producing neutrinos from muons that decay in a racetrack ring can provide extremely well understood neutrino beams for oscillation physics and the search for sterile neutrinos. The ‘‘neutrinos from STORed Muons"(nuSTORM) facility based on this idea has been introduced by Bross, Neuffer et al. The design of the nuSTORM facility and the particle tracking have been presented in the paper of Liu, et al. This paper demonstrates the recent optimization results of the pion beamline, with G4beamline simulations. The optimum choice of pion beam center momentum, a new algorithm on fitting bivariate Gaussian distribution to the pion phase space data at the downstream side of the horn, and the comparison of the beamline performance with the optics designed based on Graphite and Inconel targets are also described.

Muon-based facilities offer a unique potential to provide capabilities at both the Intensity Frontier with Neutrino Factories and the Energy Frontier with Muon Colliders ranging from the Higgs energy to the multi-TeV energy range. They rely on novel technology with challenging parameters, which are currently being evaluated by the U.S. Muon Accelerator Program (MAP). A realistic scenario for a complementary series of staged facilities with increasing complexity and significant physics potential at each stage has been developed. It takes advantage of and leverages the capabilities already planned for Fermilab, especially Project X Stage II and LBNE. Each stage is defined in such a way to provide an R&D platform to validate the technologies required for subsequent stages. The rationale and sequence of the staging process, as well as the critical issues to be addressed at each stage, are presented.

MICE, which is an acronym for Muon Ionization Cooling Experiment, is a technology demonstration which is presently assembled at the Rutherford Appleton Laboratory in Didcot, UK. MICE aims to demonstrate ionization cooling experimentally, which is an essential technology for potential future accelerators such as a muon collider. The MICE channel consists of up to 18 large bore superconducting solenoids, which produce a substantial stray field. This stray field can jeopardize the operation of electrical and electronic equipment in the MICE hall. The concept of a partial flux return yoke has been developed, which reduces the stray field in the MICE hall to a safe level. This paper discusses the engineering design of the partial return yoke.
