Book Synopsis BNL VERY LONG BASELINE EXPERIMENT WITH A SUPER NEUTRINO BEAM. by : S. A. KAHN
Download or read book BNL VERY LONG BASELINE EXPERIMENT WITH A SUPER NEUTRINO BEAM. written by S. A. KAHN and published by . This book was released on 2003 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: An upgrade to the BNL AGS could produce a very intense proton source at a relatively low cost. This proton source could produce a conventional neutrino beam with a very significant flux at large distances from the laboratory. In this paper we examine the possibility of using this neutrino beam for a very long baseline oscillation experiment where a 500 kiloton water Cherenkov detector is situated at the Homestake mine in South Dakota. We study the physics potential of a high intensity neutrino oscillation experiment with a 2540 km baseline and a peak neutrino energy of {approx}1 GeV.

Available in PDF, EPUB and Kindle. Book excerpt: An upgrade to the BNL Alternate Gradient Synchrotron (AGS) could produce a very intense proton source at a relatively low cost. Such a proton beam could be used to generate a conventional neutrino beam with a significant flux at large distances from the laboratory. This provides the possibility of a very long baseline neutrino experiment at the Homestake mine. The construction of this facility would allow a program of experiments to study many of the aspects of neutrino oscillations including CP violations. This study examines a 1 MW proton source at BNL and a large 1 megaton detector positioned at the Homestake Mine as the ultimate goal of a staged program to study neutrino oscillations.

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the feasibility of a long baseline neutrino beam facility based on a proposed upgrade to the AGS accelerator at Brookhaven National Laboratory. It assumes that the AGS is upgraded initially to a 1 MW proton driver and eventually to a 4 MW proton machine. This upgrade would provide a strong incentive for a long baseline low energy neutrino beam to study neutrino oscillations. In this paper we look at a possible long baseline experiment with a detector at Cornell, which is 350 km away from BNL.

Book excerpt: The US Long Baseline Neutrino Experiment Study was commissioned jointly by Brookhaven National Laboratory (BNL)and Fermi National Accelerator Laboratory (FNAL) to investigate the potential for future U.S. based long baseline neutrino oscillation experiments using MW class conventional neutrino beams that can be produced at FNAL. The experimental baselines are based on two possible detector locations: (1) off-axis to the existing FNAL 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 1000km. 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 FNAL aimed at a massive detector with a baseline of> 1000km have the best sensitivity to CP violation and the neutrino mass hierarchy for values of the mixing angle?13 down to 2{sup o}.
Book Synopsis Beta Beams: Neutrino Beams by : Mats Lindroos
Download or read book Beta Beams: Neutrino Beams written by Mats Lindroos and published by World Scientific. This book was released on 2009-07-24 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beta-beam concept for the generation of electron neutrino beams was first proposed by Piero Zucchelli in 2002. The idea created quite a stir, challenging the idea that intense neutrino beams only could be produced from the decay of pions or muons in classical neutrino beams facilities or in future neutrino factories. The concept initially struggled to make an impact but the hard work by many machine physicists, phenomenologists and theoreticians over the last five years has won the beta-beam a well-earned position as one of the frontrunners for a possible future world laboratory for high intensity neutrino oscillation physics. This is the first complete monograph on the beta-beam concept. The book describes both technical aspects and experimental aspects of the beta-beam, providing i) students and scientists with an insight into the possibilities offered by beta-beams; ii) facility designers with a starting point for future studies; and iii) policy makers with a comprehensive picture of the limits and possibilities offered by a beta-beam./a

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: The workshop has reviewed progress towards the future generation of neutrino oscillation experiments. These experiments will use very intense conventional neutrino beams and novel beams derived from muons or radioactive nuclei. These new facilities will provide a broad research front including muon physics and neutrino scattering experiments. The main technical challenges involve construction of very intense proton beams, targeting, effective capture of produced particles, cooling and subsequent acceleration of the resulting muons.

Book excerpt: We have investigated the physics potential of very long baseline experiments designed to measure nu_mu to nu_e oscillation probabilities. The principles of our design are to tune the beam spectrum to the resonance energy for the matter effect, and to have the spectrum cut off rapidly above this energy. The matter effect amplifies the signal, and the cut-off suppresses backgrounds which feed-down from higher energy. The signal-to-noise ratio is potentially better than for any other conventional nu_mu beam experiment. We find that a beam from Fermilab aimed at the Super-K detector has excellent sensitivity to sin2̂(2theta_13) and the sign of Delta M2̂. If the mass hierarchy is inverted, the beam can be run in antineutrino mode with a similar signal-to-noise ratio, and event rate 55% as high as for the neutrino mode. Combining the Fermilab beam with the JHF-Kamioka proposal adds very complementary information. We find good sensitivity to maximal CP violation for values of sin2̂(2theta_13) ranging from 0.001 to 0.05.

This book was released on 2002 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brookhaven National Laboratory and collaborators started a neutrino working group to identify new opportunities in the field of neutrino oscillations and explore how our laboratory facilities can be used to explore this field of research. The memo to the working group and the charge are included in Appendix I. This report is the result of the deliberations of the working group. Previously, we wrote a letter of intent to build a new high intensity neutrino beam at BNL. A new intense proton beam will be used to produce a conventional horn focused neutrino beam directed at a detector located in either the Homestake mine in Lead, South Dakota at 2540 km or the Waste Isolation Pilot Plant (WIPP) in Carlsbad, NM at 2880 km. As a continuation of the study that produced the letter of intent, this report examines several items in more detail. We mainly concentrate on the use of water Cherenltov detectors because of their size, resolution, and background rejection capability, and cost. We examine the prospects of building such a detector in the Homestake mine. The accelerator upgrade will be carried out in phases. We expect the first phase to yield a 0.4 MW proton beam and the second phase to result in a 1.0 MW beam. The details of this upgrade will be reported in a companion report. In this report we assume accelerator intensity of 1 MW for calculating event rates and spectra. We also assume a total experimental duration of 5 years with running time of 107 seconds per year. We examine the target station and the horn produced neutrino beam with focus on two topics: target and horn design for a 1 MW beam and the broad band spectrum of neutrinos from a 28 GeV proton beam.
Book Synopsis THE BNL SUPER NEUTRINO BEAM PROJECT. by : D. RAPARIA
Download or read book THE BNL SUPER NEUTRINO BEAM PROJECT. written by D. RAPARIA and published by . This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the neutrino mixing amplitudes and phase accurately, as well as the CP violation parameters, a very long base line super neutrino beam facility is needed. This is possible due to the long distance and wideband nature of the neutrino beam for the observation of several oscillations from one species of the neutrino to the other [1,2]. BNL plans to upgrade the AGS proton beam from the current 0.14 MW to higher than 1.0 MW and beyond for such a neutrino facility which consists of three major subsystems. First is a 1.5 GeV superconducting linac to replace the booster as injector for the AGS, second is the performance upgrade for the AGS itself for the higher intensity and repetition rate, and finally is target and horn system for the neutrino production. The major contribution for the higher power is from the increase of the repetition rate of the AGS form 0.3 Hz to 2.5 Hz, with moderate increase from the intensity [3]. The design consideration to achieve high intensity and low losses for the linac and the AGS will be reviewed. The target horn design for high power operation and easy maintenance will also be presented.

This book was released on 2003 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes the design of the accelerator and target systems for the AGS Super Neutrino Beam Facility. Under the direction of the Associate Laboratory Director Tom Kirk, BNL has established a Neutrino Working Group to explore the scientific case and facility requirements for a very long baseline neutrino experiment. Results of a study of the physics merit and detector performance was published in BNL-69395 in October 2002, where it was shown that a wide-band neutrino beam generated by a 1 MW proton beam from the AGS, coupled with a half megaton water Cerenkov detector located deep underground in the former Homestake mine in South Dakota would be able to measure the complete set of neutrino oscillation parameters: (1) precise determination of the oscillation parameters?m322 and sin2 2?32; (2) detection of the oscillation of?{sub {mu}}-?{sub e} and measurement of sin2 2?13; (3) measurement of?m212 sin 2?12 in a?{sub {mu}} →?{sub e} appearance mode, independent of the value of?13; (4) verification of matter enhancement and the sign of?m322; and (5) determination of the CP-violation parameter?{sub CP} in the neutrino sector. This report details the performance requirements and conceptual design of the accelerator and the target systems for the production of a neutrino beam by a 1.0 MW proton beam from the AGS. The major components of this facility include a new 1.2 GeV superconducting linac, ramping the AGS at 2.5 Hz, and the new target station for 1.0 MW beam. It also calls for moderate increase, about 30%, of the AGS intensity per pulse. Special care is taken to account for all sources of proton beam loss plus shielding and collimation of stray beam halo particles to ensure equipment reliability and personal safety. A preliminary cost estimate and schedule for the accelerator upgrade and target system are also included.

Available in PDF, EPUB and Kindle. Book excerpt: This is nal report on an Early Career Award grant began in April 15, 2010 and concluded on April 14, 2015. Alysia Marino's research is fo- cussed on making precise measurements of neutrino properties using in- tense accelerator-generated neutrino beams. As a part of this grant, she is collaborating on the Tokai-to-Kamioka (T2K) long-baseline neutrino exper- iment [6], currently taking data in Japan, and on the Deep Underground Neutrino Experiment (DUNE) design e ort for a future Long-Baseline Neu- trino Facility (LBNF) in the US. 1 She is also a member of the NA61/SHINE particle production experiment at CERN, but as that e ort is supported by other funds, it will not be discussed further here. T2K was designed to search for the disappearance of muon neutrinos () and the appearance of electron neutrinos (e), using a beam of muon neu- trino beam that travels 295 km across Japan towards the Super-Kamiokande detector. In 2011 T2K rst reported indications of e appearance [2], a pre- viously unobserved mode of neutrino oscillations. In the past year, T2K has published a combined analysis of disappearance and e appearance [1], and began collecting taking data with a beam of anti-neutrinos, instead of neutrinos, to search for hints of violation of the CP symmetry of the uni- verse. The proposed DUNE experiment has similar physics goals to T2K, but will be much more sensitive due to its more massive detectors and new higher-intensity neutrino beam. This e ort will be very high-priority particle physics project in the US over the next decade.
