Spallation neutron source GNEIS
Physics of Particles and Nuclei, 2018A brief description of the spallation pulsed neutron source and neutron TOF spectrometer GNEIS based on the 1 GeV proton synchrocyclotron of PNPI in Gatchina is presented. The main parameters of the GNEIS are given in comparison with the analogous world-class facilities.

Neutrinos at the Spallation Neutron Source
AIP Conference Proceedings, 2007The Spallation Neutron Source at Oak Ridge will provide an intense source of neutrinos in the tens of MeV range, which nicely overlaps with the supernova neutrino energy range. I will describe the Neutrinos at the SNS (νSNS) program planned to exploit this high power, high quality source for studies of neutrino cross‐sections relevant for supernova ...

Neutronics of pulsed spallation neutron sources
Reports on Progress in Physics, 2003Various topics and issues on the neutronics of pulsed spallation neutron sources, mainly for neutron scattering experiments, are reviewed to give a wide circle of readers a better understanding of these sources in order to achieve a high neutronic performance.

Optimizing moderator dimensions for neutron scattering at the spallation neutron source
Review of Scientific Instruments, 2013In this work, we investigate the effect of neutron moderator dimensions on the performance of neutron scattering instruments at the Spallation Neutron Source (SNS). In a recent study of the planned second target station at the SNS facility, we have found that the dimensions of a moderator play a significant role in determining its surface brightness. A

Option for spallation neutron sources
Journal of Fusion Energy, 1989Spallation reactions are a very important option for efficient neutron sources appropriate for fusion materials testing. An “option of this option” is the EURAC concept, which makes use of short-term accelerator technology in the cheapest way and is proved to provide the needed neutron flux to verify fast experiments on fusion materials performance ...

Japanese spallation neutron source
Applied Physics A: Materials Science & Processing, 2002The Japanese ‘Joint Project’ is a new project to pursue frontiers in particle physics, nuclear physics, materials science, life science and nuclear technology, using a new proton-accelerator complex with the highest beam power in the world. This project had been jointly proposed by the High Energy Accelerator Research Organization (KEK) and the Japan ...

Neutron Scattering with Spallation Sources
Physics Today, 1985The other articles in this issue are concerned with the variety of science that goes on at reactor-based neutron sources. Such sources, based on nuclear fission, have been available since 1942. It has been known since the 1930s that neutrons could be produced through spallation by sending a charged beam of accelerated protons or electrons into a target.

Neutron spallation sources in Europe
Nuclear Physics B - Proceedings Supplements, 1996After a brief general and historical discussion, the main design features of spallation sources are described. At the present time, Europe not only has the world-leading pulsed neutron spallation source, the SNS-ISIS at RAL, UK, but it is on the point of commissioning a world-leading continuous cyclotron-driven source, the SINQ at PSI, Switzerland ...

The spallation-neutron-source project SINQ
Physica B+C, 1986SINQ is a continuous spallation-neutron source which is planned to be attached to the existing proton cyclotron at the Swiss Institute for Nuclear Research (SIN) after its upgrading to higher currents. The neutron-flux characteristics will be similar to those of a medium-flux reactor, but particular advantages are expected in the cold neutron region ...

Spallation sources for neutron scattering
Physics Today, 1982Low-energy neutrons are particulary well suited to probe crystalline, glassy and biological materials. The de Broglie wavelength of a thermal neutron is of the same order as interatomic spacings, and its anomalously high cross section for scattering off hydrogen nuclei makes it an especially useful probe for hydrogenous substances. Furthermore, because
