This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: After considering supernova shock effects, Mikheyev-Smirnov-Wolfenstein effects, neutrino collective effects, and Earth matter effects, the detection of supernova neutrinos at the China Spallation Neutron Source is studied and the expected numbers of different flavor supernova neutrinos observed through various reaction channels are calculated with the neutrino energy spectra described by the Fermi-Dirac distribution and the "beta fit" distribution respectively. Furthermore, the numerical calculation method of supernova neutrino detection on Earth is applied to some other spallation neutron sources, and the total expected numbers of supernova neutrinos observed through different reactions channels are given.
Download or read book Low Energy Neutrino Nucleus Interactions at the Spallation Neutron Source written by Samuel Hedges and published by Springer. This book was released on 2024-09-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis highlights the development and analysis of multiple neutrino detectors deployed to the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory as part of the COHERENT experiment. It includes a preliminary measurement of the neutrino-induced neutron cross section on lead, and analysis that led to the first inclusive electron-neutrino charged-current measurement on iodine. These results add to the small number of inelastic neutrino-nucleus cross sections measured in this energy range, which are useful for understanding supernova and solar neutrino detection sensitivity. Additionally, it discusses preliminary work for and design of COHERENT’s ton-scale NaI coherent elastic neutrino-nucleus scattering (CEvNS) detector, currently being deployed to the SNS. Finally, it includes information on a campaign to measure the nuclear recoil quenching factor of NaI using multiple crystals, attempting to resolve inconsistencies with existing measurements.
Download or read book Basic Physics with Spallation neutron Sources written by and published by . This book was released on 1994 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neutron has unique intrinsic properties widely used in basic and applied sciences. The neutron plays a well-known role in applied sciences and technology and is a unique probe well suited for the exploration of condensed-matter properties. But the neutron is also used for many other basic-physics studies, including nuclear physics, particle physics, fundamental physics, astrophysics, and cosmology. These last studies are briefly reviewed in this paper. Spallation-neutron sources today have unmatched neutron-beam properties for such studies and have great potential in future technological developments whereby these studies could be carried out under much improved conditions.

Available in PDF, EPUB and Kindle. Book excerpt: This detailed and comprehensive reference to spallation -- from the foundations to the latest applications is the only work of its kind and is written by two internationally renowned researchers. Clearly divided into three parts, it begins with the basic principles, while the second part describes the proton-nucleus and proton-matter experiments so-called thin and thick target experiments in terms of secondary particle production as hadrons, pions, muons, photons, electrons, light and intermediate masses, isotope production, heating and energy deposition and materials damage. Many of the experiments are associated with studies, investigations and the construction of spallation neutron sources since 1975 with emphasis on the most recent developments. The final part on technology and applications describes the various engineering problems associated with high intensity neutron spallation sources, ATW's, the needed accelerator systems, material and neutron issues, and high energy neutron source shielding aspects. A must-have for engineers and physicists working in or entering this field.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: We study the detection of accelerator neutrinos produced at the China Spallation Neutron Source (CSNS). Using the code FLUKA, we have simulated the production of neutrinos in a proton beam on a tungsten target and obtained the yield efficiency, numerical flux, and average energy of different flavors of neutrinos. Furthermore, detection of these accelerator neutrinos is investigated in two reaction channels: neutrino-electron reactions and neutrino-carbon reactions. The expected numbers of different flavors of neutrinos have also been calculated.

Book excerpt: The COHERENT collaboration's primary objective is to measure coherent elastic neutrino- nucleus scattering (CEvNS) using the unique, high-quality source of tens-of-MeV neutrinos provided by the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). In spite of its large cross section, the CEvNS process has never been observed, due to tiny energies of the resulting nuclear recoils which are out of reach for standard neutrino detectors. The measurement of CEvNS has now become feasible, thanks to the development of ultra-sensitive technology for rare decay and weakly-interacting massive particle (dark matter) searches. The CEvNS cross section is cleanly predicted in the standard model; hence its measurement provides a standard model test. It is relevant for supernova physics and supernova-neutrino detection, and enables validation of dark-matter detector background and detector-response models. In the long term, precision measurement of CEvNS will address questions of nuclear structure. COHERENT will deploy multiple detector technologies in a phased approach: a 14-kg CsI[Na] scintillating crystal, 15 kg of p-type point-contact germanium detectors, and 100 kg of liquid xenon in a two-phase time projection chamber. Following an extensive background measurement campaign, a location in the SNS basement has proven to be neutron-quiet and suitable for deployment of the COHERENT detector suite. The simultaneous deployment of the three COHERENT detector subsystems will test the N=2 dependence of the cross section and ensure an unambiguous discovery of CEvNS. This document describes concisely the COHERENT physics motivations, sensitivity and plans for measurements at the SNS to be accomplished on a four-year timescale.

Download or read book Neutron Scattering Fundamentals written by Francisco J. Bermejo and published by Elsevier Inc. Chapters. This book was released on 2013-11-22 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter reviews the most significant developments that have taken place in the design, construction, and operation of new neutron sources as well as the refurbishment programs of others already serving the neutron-scattering community. Such advances in neutron production devices are to be considered in conjunction with impressive achievements in the optimization of neutron delivery systems as well as in neutron instrumentation which overall resulted in a truly remarkable improvement in neutron count rates. As a result, the capabilities of experimental neutron sources are nowadays larger than ever before, despite there being fewer sources available. It is also worth remarking the coming into line of compact, accelerator-driven neutron sources as well as work carried out at small research reactors which, as exemplified during the past decade, have played an important role in helping the large, user-based facilities to carry out development work geared toward the achievement of full performance.
Download or read book Parity Violation Time Reversal and the Neutron written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than half a century, low energy neutrons have been used to elucidate important issues related to the understanding of fundamental symmetries, the determination of fundamental constants, and the testing of basic theories in nuclear and particle physics. Currently investigations with 'Cold' and 'Ultra Cold' neutrons are addressing questions related to the origin of time reversal asymmetry, the unitarity of the CKM matrix, and the nature of the hadronic weak interaction. Current and proposed measurements of the neutron electric dipole moment, neutron beta decay and nucleon-nucleon parity violation will be reviewed. The opportunities for this work at the accelerator based Spallation Neutron Source, currently under construction at Oak Ridge National Laboratory, will be discussed.
