Available in PDF, EPUB and Kindle. Book excerpt: A simple, straightforward, and economic experiment utilizing a set of water Cherenkov counters is proposed to search for neutrino oscillations in the AGS neutrino beam. The detector will be movable and will be able to provide reasonable counting rates up to 2 km downstream of the pion decay tunnel. Whereas previous accelerator experiments have sought to increase the ratio l/p (with l the neutrino path length and p its momentum) by decreasing p, increasing l is suggested instead. Further, by making measurements at several different values of l with the same apparatus, many sources of systematic error are eliminated. The experiment will measure beam-associated muon- and electron-type events at each position. A change in the ratio of muon- to electron-type events as a function of position would be evidence for .nu./sub .mu./ + .nu./sub e/ oscillations. Sensitivity in terms of (.delta.m)2 (the square of the mass difference in the mass eigenstates) can be as low as 0.1 eV2, for full mixing, which is below the most probable value found by Reines et al for .delta.m2 in their electron neutrino reactor experiment. This experiment would be parasitic, running behind the usual neutrino beam experiments, assuming the nominal beam energy (peaked at 1 GeV), and would thus make a minimal demand on AGS support. It is suggested that the first two measurements be made inside the Isabelle tunnel at the points of intersection with the AGS neutrino beam. No further excavations would be required, and the data could be taken before ISA equipment is installed.

Available in PDF, EPUB and Kindle. Book excerpt: Two groups have submitted major proposals for neutrino oscillation searches at BNL. Both are two detector experiments with a close detector at approx. = 100m and a far detector at approx. = 900m. While the details of the experiments are quite different, both groups expect to obtain nu/sub .mu./ disappearance limits of delta m2sin2 theta approx. = 0.1 - 0.2 for small mass difference and sin22 theta at the few percent level for the most sensitive delta m2(approx. = 25eV2). Since both detectors are designed to identify electrons as well as muons they expect to obtain significant limits on nu/sub e/ appearance (nu/sub .mu./ .-->. nu/sub e/). Each has received approval for a single detector (Phase I) experiment with the two detector phase (Phase II) still pending. The present status of the single detector experiments is detailed. (WHK).

Book excerpt: The present paper reports on preliminary results from the E 816 experiment at Brookhaven National Laboratory. E 816 is the continuation of a 1984 experiment (PS 191) which was devoted to a neutrino decay search in the CERN PS neutrino beam. No candidate was seen, but a study of neutrino interactions in the calorimeter indicated an anomalous electron production. The statistics was too low and the experiment has been rerun in spring 86 at BNL to look specifically, with an improved detector for nu/sub e/ arising from a low energy nu/sub .mu./ beam. The results presented here are preliminary for at least two reasons: first the collaboration is presently running a calibration test which results are not included here; second, only 1/3 of the neutrino data is used, and no mention will be made to antineutrino data for which the analysis is still going on. This report will directly start with a description of our apparatus, followed by the data analysis.

Available in PDF, EPUB and Kindle. Book excerpt: The authors present a design for a multi-detector long baseline neutrino oscillation experiment at the BNL AGS. It has been approved by the BNL-HENP-PAC as AGS Experiment 889. The experiment will search for oscillations in the [nu]{sub [mu]}, disappearance channel and the [nu]{sub {mu}} ↔ [nu]{sub e} appearance channel by means of four identical neutrino detectors located 1, 3, 24, and 68km from the AGS neutrino source. Observed depletion of the [nu]{sub {mu}} flux (via quasi-elastic muon neutrino events, [nu]{sub {mu}}n → {mu}−p) in the far detectors not attended by an observed proportional increase of the [nu]{sub e} flux (via quasi-elastic electron neutrino events, [nu]{sub e}n → e−p) in those detectors will be prima facie evidence for the oscillation channel [nu]{sub {mu}} ↔ [nu]{sub {tau}}. The experiment is directed toward exploration of the region of the neutrino oscillation parameters [Delta]m2 and sin22[theta], suggested by the Kamiokande and IMB deep underground detectors but it will also explore a region more than two orders of magnitude larger than that of previous accelerator experiments. The experiment will run in a mode new to BNL. It will receive the fast extracted proton beam on the neutrino target approximately 20 hours per day when the AGS is not filling RHIC. A key aspect of the experimental design involves placing the detectors 1.5 degrees off the center line of the neutrino beam, which has the important advantage that the central value of the neutrino energy (≈ 1 GeV) and the beam spectral shape are, to a good approximation, the same in all four detectors. The proposed detectors are massive, imaging, water Cherenkov detectors similar in large part to the Kamiokande and IMB detectors. The design has profited from their decade-long experience, and from the detector designs of the forthcoming SNO and SuperKamiokande detectors.

Download or read book Search for Oscillations of a Long-lived Muon Neutrino Beam written by and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the time evolution of a long-lived .nu./sub mu/ beam is being performed at Brookhaven National Laboratory (Experiment 704). The proton momentum (1.5 GeV/c/sup 2/) is chosen to concentrate the .nu./sub mu/ flux at very low energy where all background reactions are kinematically suppressed. Sensitivity to oscillations at large proper times tau varies as l/p (where l is the flight length and p is the momentum of the neutrino) is greatly enhanced by the resulting low neutrino momentum. Transformations .nu./sub mu/ .-->. .nu./sub e/ are sensed via .nu./sub e/n .-->. e/sup -/p. An early exploratory test using the neutrino detector of the BNL elastic neutrino-proton scattering experiment will be run during 1977. A 200 ton detector for a definitive experiment is also discussed. 14 references.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of neutrino masses is of fundamental importance. Neutrino oscillations seem to be the only tool available to us to unravel the pattern of neutrino masses and, perhaps, shed some light on the origin of masses in general. The NuMI neutrino beam line and the MINOS experiment represent a major investment of US High Energy Physics in the area of neutrino physics. the forthcoming results could decisively establish neutrino oscillations as the underlying physics mechanism for the atmospheric[nu][sub[mu]] deficit and provide a precise measurement of the corresponding oscillation parameters, [Delta]m[sub 32][sup 2] and sin[sup 2] 2[theta][sub 23]. This, however, is just a beginning of a long journey into uncharted territories. The key to these new territories is the detection of[nu][sub[mu]][yields][nu][sub e] oscillations associated with the atmospheric[nu][sub[mu]] deficit, controlled by the little known mixing angle sin[sup 2]2[theta][sub 13]. A precise measurement of the amplitude of these oscillations will enable a determination of the pattern of the mass hierarchy of neutrinos. If the solar neutrino experiments determine that the value[Delta]m[sub 12][sup 2] is in the range of 10[sup -5]-10[sup -4] eV[sup 2] then the measurement of the CP violation in the neutrino sector may well be within our reach. The full potential of the NuMI neutrino beam can be exploited by complementing the MINOS detector, under construction, with a new detector(s) placed at some off-axis position and collecting data in parallel with MINOS. The first phase of the proposed program includes a new detector, optimized for[nu][sub e] detection, with a fiducial mass of the order os 20 kton and exposed to neutrino and antineutrino beams. In a five year run its sensitivity to the[nu][sub[mu]][yields][nu][sub e] oscillations will be at least a factor of ten beyond the current limit. The future direction of the program will depend on the results of this first phase, but it is very likely that it will be combination of a significant increase of the neutrino beam intensity via an upgraded proton source and an increase of the detector mass by a factor of five or so. Depending on the circumstances, the goals of Phase II may be a further increase of the sensitivity of a search for[nu][sub[mu]][yields][nu][sub e] oscillations, or, perhaps, a measurement of the CP violating phase[delta] in the lepton sector.

Download or read book Detectors for the MINOS Long-baseline Neutrino Oscillation Experiment written by and published by . This book was released on 1996 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MINOS long-baseline experiment will use an intense neutrino beam, generated by Fermilab's Main Injector accelerator, and 730 km flight path to search for neutrino oscillations. The 10,000 ton MINOS far detector will utilize toroidally magnetized steel plates interleaved with track chambers to reconstruct event topologies and to measure the energies of the muons, hadrons and electromagnetic showers produced by neutrino interactions. The MINOS collaboration is currently developing three alternative technologies for the track chambers: 'Iarocci' tubes (operated in either limited streamer or saturated proportional mode), RPC's (with either glass or ABS plates), and scintillator (either liquid or plastic) with wavelength shifting fiber readout. The technology choice will be made in mid 1997 based on the projected performance and cost of the 32,000 m2 active detector system.

Available in PDF, EPUB and Kindle. Book excerpt: The US Long Baseline Neutrino Experiment Study was commissioned jointly by Brookhaven National Laboratory and Fermi National Accelerator Laboratory to investigate the potential for future U.S. based long baseline neutrino oscillation experiments beyond the currently planned program. The Study focused on MW class convention at neutrino beams that can be produced at Fermilab or BNL. The experimental baselines are based on two possible detector locations: (1) off-axis to the existing Fermilab NuMI beamline at baselines of 700 to 810 km and (2) NSF's proposed future Deep Underground Science and Engineering Laboratory (DUSEL) at baselines greater than 1000 km. Two detector technologies are considered: a megaton class Water Cherenkov detector deployed deep underground at a DUSEL site, or a 100kT Liquid Argon Time-Projection Chamber (TPC) deployed on the surface at any of the proposed sites. The physics sensitivities of the proposed experiments are summarized. We find that conventional horn focused wide-band neutrino beam options from Fermilab or BNL aimed at a massive detector with a baseline of> 1000 km have the best sensitivity to CP violation and the neutrino mass hierarchy for values of the mixing angle {theta}{sub 13} down to 2.2{sup o}.

Available in PDF, EPUB and Kindle. Book excerpt: This is a report on a search for $\nu\sb{\mu}\to\nu\sb{e}$ oscillations using the E776 detector at Brookhaven National Laboratory with Professor T. A. O'Halloran as my advisor. The detector consisted of a large fiducial mass electromagnetic calorimeter followed by a toroidal muon spectrometer and was located 1 km from the target at the AGS. 1.43 $\times$ 10$\sp{19}$ protons on target were collected in the wide band beam with a peak neutrino energy of 1.1 GeV. No evidence for neutrino oscillations was observed. The 90% confidence limits obtained are $\Delta\ m\sp2\leq0.107\ eV\sp2$ for large mixing angle, and sin$\sp2\ 2\theta\leq$ 7.7 $\times$ 10$\sp{-3}$ in the limit of large $\Delta\ m\sp2$.
