Neutron spallation sources in Europe

Nuclear Physics B - Proceedings Supplements, 1996
After 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, 2000
Neutronics 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 ...

Spallation neutron source (SNS)

AIP Conference Proceedings, 2002
The 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 ...

Neutron macromolecular crystallography at the European spallation source

2020
The 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, 2004
The 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 ...

Status of the spallation neutron source

Physica C: Superconductivity, 2006
The 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.

The corrosion of materials in spallation neutron sources

JOM, 1998
Efforts 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.

Neutron sensing at spallation neutron sources by SERS

Applied Surface Science
Neutron detectors are paramount in many applications from medical science to homeland security and aero-space. A miniaturized solid-state device based on a nanostructured-gold thin film grown by pulsed laser ablation under deposition-controlled conditions and functionalized with a monolayer of 4-mercaptophenyboronic acid (4-MPBA) was fabricated as a ...

The U. K. Spallation Neutron Source

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1980
Abstract Pulsed neutron sources offer an attractive route for the realization of effective fluxes greater than those currently available from high flux reactors. The spallation neutron source now under construction at the Rutherford Laboratory will produce intense bursts of fast neutrons through interactions of 800 MeV protons with a ...

Spallation neutron sources for neutron beam research

Contemporary Physics, 1978
Abstract The major components of a spallation neutron source for neutron beam research are: an accelerator to produce intense bursts of energetic particles such as protons of 800 MeV; a target of a heavy material thick enough to absorb the majority of the energy of bombarding particles; an assembly of moderators and reflectors to slow the neutrons ...
