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 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 ...

Neutronic Design Studies for the Spallation Neutron Source
Nuclear Technology, 2000Neutronics analyses are now in progress to support initial selection of target system design features, materials, geometry, and component sizes for the proposed Spallation Neutron Source. Calculations have been performed to determine the neutron, proton, heavy-ion, and gamma-ray flux spectra as a function of time, energy, and space for the major ...

Neutron macromolecular crystallography at the European spallation source
2020The long-pulse spallation source of the European Spallation Source-a facility under construction in Lund, Sweden-is well suited for macromolecular crystallography experiments. We review briefly the particular properties of the long-pulse source and the associated high-brilliance moderators from the point of view of instrument design.

The status of the spallation neutron source ion source
Review of Scientific Instruments, 2004The ion source for the spallation neutron source (SNS) is a radio-frequency, multicusp source designed to deliver 45 mA of H− to the SNS accelerator with a pulse length of 1 ms and repetition rate of 60 Hz. A total of three ion sources have been fabricated and commissioned at Lawrence Berkeley National Laboratory and subsequently delivered to the SNS ...

Spallation neutron source (SNS)
AIP Conference Proceedings, 2002The Spallation Neutron Source [1], located at Oak Ridge, TN, is a state-of-the-art neutron-scattering facility presently under construction as a collaborative effort of six national laboratories. The facility is comprised of a high-power particle-accelerator system, a liquid-mercury target-moderator system, and a suite of world-class scientific ...

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

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 ...

The corrosion of materials in spallation neutron sources
JOM, 1998Efforts to measure the real-time corrosion rates of alloy 718 during 800 MeV proton radiation at currents up to 1 mA are reported. Specially designed corrosion probes, which incorporate ceramic seals, were mounted in a water manifold that allowed samples to be directly exposed to the proton beam at the Los Alamos Neutron Science Center.

Status of the spallation neutron source
Physica C: Superconductivity, 2006The superconducting linac for the spallation neutron source is being commissioned. Seventy seven of the 81 niobium cavities resonating at 805 MHz have been installed in the SNS tunnel in 11 medium beta (0.61) cryomodules each containing three cavities and 11 (presently) high beta (0.81) cryomodules each with four cavities.
