This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and latest astrophysical data.
The conclusions of the Physics Working Group international scoping study a future Neutrino Factory and super-beam facility (the ISS) are presented. ISS was carried by community between NuFact05, 7th International Workshop on Factories Superbeams, Laboratori Nazionali di Frascati, Rome, June 21-26, 2005) NuFact06 (Ivine, California, 24{30 August 2006). physics case for an extensive experimental programme to understand properties neutrino is presented role high-precision measurements...
This document summarizes the work of Accelerator Working Group (AWG) International Scoping Study (ISS) a Future Neutrino Factory and Superbeam Facility. The main goal activity was to reach consensus on baseline design for complex, including proton driver parameters, choice target, front-end design, acceleration system decay ring geometry. Another explore commonality, if any, between those or Beta Beam facility. In general, requirements either latter facilities are less stringent than...

A novel single-particle technique to measure emittance has been developed and used characterise seventeen different muon beams for the Muon Ionisation Cooling Experiment (MICE). The beams, whose mean momenta vary from 171 281 MeV/c, have emittances of approximately 1.5--2.3 \pi mm-rad horizontally 0.6--1.0 vertically, a horizontal dispersion 90--190 mm momentum spreads about 25 MeV/c. There is reasonable agreement between measured parameters results simulations. are found meet requirements MICE.

Finally, beam loss in generated by operation evaluated as function rate, operating parameters derived.
The Muon Ionization Cooling Experiment (MICE) will perform a detailed study of ionization cooling to evaluate the feasibility technique. To carry out this program, MICE requires an efficient particle-identification (PID) system identify muons. Electron-Muon Ranger (EMR) is fully-active tracking-calorimeter that forms part PID and tags muons traverse channel without decaying. detector capable identifying electrons with efficiency 98.6%, providing purity for beam exceeds 99.8%.

The international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams momentum between 140 and 240\,MeV/c at the Rutherford Appleton Laboratory ISIS facility. measurement in MICE relies on selection pure sample muons that traverse experiment. To make this selection, Beam is designed to deliver beam less than $\sim$1\% contamination. final employs particle-identification (PID) system upstream downstream cell. PID includes...
Abstract Accelerated muon beams have been considered for the next-generation studies of high-energy lepton–antilepton collisions and neutrino oscillations. However, high-brightness not yet produced. The main challenge acceleration storage stems from large phase-space volume occupied by beam, derived production mechanism muons through decay pions. beam can be decreased ionization cooling. Here we show that cooling leads to a reduction in transverse emittance traverse lithium hydride or liquid...
The Muon Ionization Cooling Experiment (MICE) will demonstrate the principle of muon beam phase-space reduction via ionization cooling. cooling be required for proposed Neutrino Factory or Collider. before and after cell must measured precisely. This is achieved using two scintillating-fibre trackers, each placed in a solenoidal magnetic field. paper describes software reconstruction fibre trackers: GEANT4 based simulation; implementation geometry; digitisation; space-point reconstruction;...
In line with its terms of reference the ICFA Neutrino Panel has developed a roadmap for international, accelerator-based neutrino programme. A "roadmap discussion document" was presented in May 2016 taking into account peer-group-consultation described Panel's initial report. The used to solicit feedback from community---and more broadly, particle- and astroparticle-physics communities---and various stakeholders roadmap, conclusions recommendations this document take comments received...
The properties of the neutrino provide a unique window on physics beyond that described by standard model. study subleading effects in oscillations, and race to discover CP-invariance violation lepton sector, has begun with recent discovery ${\ensuremath{\theta}}_{13}>0$. measured value ${\ensuremath{\theta}}_{13}$ is large, emphasizing need for facility at which systematic uncertainties can be reduced percent level. factory, intense beams are produced from decay muons, been shown outperform...
High-brightness muon beams of energy comparable to those produced by state-of-the-art electron, proton and ion accelerators have yet be realised. Such the potential carry search for new phenomena in lepton-antilepton collisions extremely high also provide uniquely well-characterised neutrino beams. A beam may created through decay pions interaction a with target. To produce high-brightness from such source requires that phase space volume occupied muons reduced (cooled). Ionization cooling...
