Future experiments with neutrino superbeams, beta-beams, and neutrino factories

Description: This report describes the goals of the next generations of accelerator-based neutrino experiments, and the various strategies that are being considered to achieve those goals. Because these next steps in the field are significantly different from the current or previous steps, novel techniques must be considered for both the detectors and the neutrino beams themselves. We consider not only conventional neutrino beams created by decays of pions, but also those which could be made by decays of beams of relativistic isotopes (so-called ''beta-beams'') and also by decays of beams of muons (neutrino factories).

NuTeV SSQT performance

Description: The NuTeV experiment (E815) took data during the 1996-1997 Fermilab fixed target run. The experiment used the sign-selected-quadrupole- train (SSQT) in its neutrino beamline to choose either a neutrino or an anti- neutrino beam. This note summarizes the performance of the SSQT, as measured by the beamline monitoring devices, the observed {nu}{sub {mu}} and {anti {nu}}{sub {mu}} fluxes, and the upper limit on the wrong sign neutrino contamination.

SENSITIVITIES OF FUTURE LONG BASELINE EXPERIMENTS IN THE U.S.

Description: Sensitivities to neutrino oscillation parameters for possible very long baseline neutrino oscillation experiments are discussed. The reach for observing a non-zero mixing angle {theta}{sub 13}, establishing CP violation and determining the mass hierarchy are compared between various experimental options. Different possibilities for neutrino beams are briefly described, as well as the assumptions about the performance of a large water Cherenkov and liquid Argon detector.

Measurement of neutrino velocity with the MINOS detectors and NuMI neutrino beam

Description: The velocity of a {approx}3 GeV neutrino beam is measured by comparing detection times at the Near and Far detectors of the MINOS experiment, separated by 734 km. A total of 473 Far Detector neutrino events was used to measure (v -c)/c = 5.1{+-}2.9x10{sup -5} (at 68% C.L.). By correlating the measured energies of 258 charged-current neutrino events to their arrival times at the Far Detector, a limit is imposed on the neutrino mass of m{sub v} < 50 MeV/c{sup 2} (99% C.L.).

Solid Target Studies for Muon Colliders And Neutrino Beams

Description: This paper presents preliminary results from an ongoing post-irradiation analysis of materials that have been irradiated at the Brookhaven National Laboratory (BNL) Isotope facility. The effort is part of an experimental study that focuses on how prone to irradiation damage these materials are and thus what is their potential in playing the role of high power targets in the neutrino superbeam and the muon collider initiatives.

Proposal for continuously-variable neutrino beam energy for the NuMI facility

Description: The NuMI Facility was intended to be flexibly changed between 3 energies of beams, LE, ME, and HE. However, the changeover requires extensive downtime to move and realign horns and the target. We propose to implement a flexible arrangement where the target can be remotely moved in the beamline direction to change the beam energy and the horns remain fixed. In addition to having the attractive feature of keeping the horn optics fixed, the motion of the target can be performed more quickly and hence on a more frequent basis. We discuss potential increases in statistics in the high energy region, systematic cross-checks available, and the improved beam monitoring capabilities with such variable energy beams.

Future possibilities with Fermilab neutrino beams

Description: We will start with a brief overview of neutrino oscillation physics with emphasis on the remaining unanswered questions. Next, after mentioning near future reactor and accelerator experiments searching for a non zero {theta}{sub 13}, we will introduce the plans for the next generation of long-baseline accelerator neutrino oscillation experiments. We will focus on experiments utilizing powerful (0.7-2.1 MW) Fermilab neutrino beams, either existing or in the design phase.

STUDIES OF DEEP INELASTIC DIFFERENTIAL DISTRIBUTIONS AT HIGH ENERGIES FOR neutrino anti-neutrino BEAMS

Description: We propose as the initial experiment in the new dichromatic V detector to make a systematic study of deep inelastic cross sections. This experiment will use the present target-detector remounted. A new magnet spectrometer system will be installed giving both better resolution and acceptance. An improved dichromatic beam will also give better information on the incident 13 neutrino energy. We propose 1000 hours of running with > 10{sup 13} ppp for this experiment.

Long Baseline Neutrino Beams and Large Detectors

Description: It is amazing to acknowledge that in roughly 70 years from when the existence of the neutrino was postulated, we are now contemplating investigating the mysteries of this particle (or particles) requiring and utilizing detectors of 300 ktons , distances of 1,000-2,000 kilometers, beam intensities of megawatts and underground depth of 5,000 feet. This evolution has evolved slowly, from the experimental discovery of the neutrino in 1956, to the demonstration that there were two neutrinos in 1962 and three and only three by 1991. The great excitement occurred in the 2000's coming from the study of solar and atmospheric neutrinos in which neutrinos were observed to oscillate and therefore have mass. Although the absolute mass of any of the neutrinos has yet to be determined (the upper limit is less than I electron volt) the difference in this square of these masses has been measured, yielding a value of (2.3 {+-} .2) 10{sup -3} ev{sup 2} for atmospheric neutrinos and (7.6 {+-} .2) 10{sup -5} ev{sup 2} for solar neutrinos. In addition their mixing angles were found to be 45{sup o} for atmospheric neutrinos and 34{sup o} for solar neutrinos. This present state of knowledge on neutrinos is pictorially displayed in Fig. 1. Of course, mixing between flavors had already been observed in the quark sector as exemplified by the Cabbibo-Kobayashi-Meskawa Matrix. It was therefore natural to extend this formalism to the lepton sector involving unitary 3 x 3 matrices and one CP violating phase. This is shown in Fig. 2 for the two sectors, quark and leptons including the Jarlskog invariant (J).

Search for Muon Neutrino Disappearance in a Short-Baseline Accelerator Neutrino Beam

Description: We report a search for muon neutrino disappearance in the {Delta}m{sup 2} region of 0.5--40 eV{sup 2} using data from both Sci-BooNE and MiniBooNE experiments. SciBooNE data provides a constraint on the neutrino flux, so that the sensitivity to {nu}{sub {mu}} disappearance with both detectors is better than with just MiniBooNE alone. The preliminary sensitivity for a joint {nu}{sub {mu}} disappearance search is presented.

Accelerator neutrino program at Fermilab

Description: The accelerator neutrino programme in the USA consists primarily of the Fermilab neutrino programme. Currently, Fermilab operates two neutrino beamlines, the Booster neutrino beamline and the NuMI neutrino beamline and is the planning stages for a third neutrino beam to send neutrinos to DUSEL. The experiments in the Booster neutrino beamline are miniBooNE, SciBooNE and in the future microBooNE, whereas in the NuMI beamline we have MINOS, ArgoNut, MINERVA and coming soon NOvA. The major experiment in the beamline to DUSEL will be LBNE.

The physics potential of neutrino beams from muon storage rings

Description: High-intensity neutrino beams could be produced using a very intense muon source, and allowing the muons to decay in a storage ring containing a long straight section. Taking the parameters of muon source designs that are currently under study for future high luminosity muon colliders, the characteristics of the neutrino beams that could be produced are discussed and some examples of their physics potential given. It is shown that the neutrino and antineutrino beam intensities may be sufficient to produce hundreds of neutrino interactions per year in a detector on the far side of the Earth.

High intensity muon storage rings for neutrino production: Lattice design

Description: Five energies, 250, 100, 50, 20, and 10 GeV, have been explored in the design of a muon storage ring for neutrino-beam production. The ring design incorporates exceptionally long straight sections with large beta functions in order to produce an intense, parallel neutrino beam via muon decay. To emphasize compactness and reduce the number of muon decays in the arcs, high-field superconducting dipoles are used in the arc design.

Physics with a millimole of muons

Description: The eventual prospect of muon colliders reaching several TeV encourages us to consider the experimental opportunities presented by very copious stores of muons, approaching 10{sup 21} per year. I summarize and comment upon some highlights of the Fermilab Workshop on Physics at the First Muon Collider and at the Front End of a Muon Collider. Topics include various varieties of {mu}{mu} colliders, {mu}p colliders, and applications of the intense neutrino beams that can be generated in muon storage rings.

How well do we need to know the beam properties at a neutrino factory?

Description: In principle, a neutrino factory can produce a beam with a well known {nu}{sub e} and {nu}{sub {mu}} flux. In practice, the uncertainties on the muon beam properties will introduce uncertainties into the calculated neutrino fluxes. The authors explore the relationship between the beam systematics and the systematic uncertainties on predicted event rates at a far site. The desired precision with which they must know the beam momentum, direction, divergence, momentum spread, and polarization are discussed.
