Overview of the Neutrinos from Stored Muons Facility - nuSTORM

Abstract

A: Neutrino beams produced from the decay of muons in a racetrack-like decay ring (the so called Neutrino Factory) provide a powerful way to study neutrino oscillation physics and, in addition, provide unique beams for neutrino interaction studies. The Neutrinos from STORed Muons (nuSTORM) facility uses a neutrino factory-like design. Due to the particular nature of nuSTORM, it can also provide an intense, very pure, muon neutrino beam from pion decay. This so-called "Neo-conventional" muon-neutrino beam from nuSTORM makes nuSTORM a hybrid neutrino factory.In this paper we describe the facility and give a detailed description of the neutrino beams that are available and the precision to which they can be characterized. We then show its potential for a neutrino interaction physics program and present sensitivity plots that indicate how well the facility can perform for short-baseline oscillation searches. Finally, we comment on the performance potential of a "Neo-conventional" muon neutrino beam optimized for long-baseline neutrino-oscillation physics.

The quest for new physics with the Physics Beyond Colliders programme

“…Another proposed SPS-based facility is the Neutrinos from Stored Muons (nuSTORM) project, which is designed to deliver a neutrino-nucleus scattering programme using beams of neutrinos from the decay of muons confined within a storage ring. The SPS would provide the primary proton beam for muon production and offers a credible location for fast extraction towards a new experimental area 20 .…”

Neutrino trident scattering at near detectors

“…3, we discuss the trident event rates and kinematic distributions at the near detectors of several present and future neutrino oscillation experiments based on LAr technology: the three detectors of the Short-Baseline Neutrino (SBN) Program at Fermilab [20] and the near detector for the long-baseline Deep Underground Neutrino Experiment (DUNE) [21,22], also located at Fermilab. We also consider the potential gains from an optimistic future facility: a 100 t LAr detector subject to the novel low-systematics neutrino beam of the Neutrinos from STORed Muons (νSTORM) project [23,24]. We discuss the sources of background events at these facilities, providing a GENIE-level analysis [25] of how to reduce these backgrounds and assessing the impact they are expected to have on the trident measurement.…”

“…The neutrino fluxes, assuming a central µ + momentum of 3.8 GeV/c in the storage ring, are taken from Ref. [24] and are shown in Fig. 7.…”

“…We start our study with the three detectors of the SBN program, one of which, µBooNE, is already installed and taking data at Fermilab. These three LAr time projection chamber detectors are located along the Booster Neutrino Beam line which is by [42]), SBND (top right, [20]) and νSTORM (bottom left, [24]) and of the cross sections for the various trident modes (bottom right). The fluxes at µBooNE and ICARUS are similar to the one shown for SBND when normalized over distance.…”

Future Collider Options for the US

“…The IMCC design assumes siting at CERN where protons are extracted from the PS using land close to the TTf10 line. However, the nuSTORM siting plan at Fermilab [50] using the Main Injector offers many attractive features for supporting a Muon Collider demo facility feeding an experimental neutrino program with a beam from muons or kaons. Figure 12 shows the Fermilab nuSTORM facility layout that was fully detailed in the nuSTORM Project Definition Report [51].…”
