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 ...

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 ...

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 ...

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.

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 ...

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 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 scattering instrumentation at the Spallation Neutron Source

SPIE Proceedings, 2002
The Spallation Neutron Source (SNS) is an accelerator-based short-pulse neutron scattering facility designed to provide an order of magnitude more power than the most powerful existing facility of this type. The SNS is being constructed at Oak Ridge National Laboratory and is on schedule for completion in 2006.

On the neutronics of SINQ, a continuous spallation neutron source

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1986
Abstract The paper gives a short technical description of the principles of SINQ, the reference design of which is based on neutronics investigations at various mock-up systems. We present some of these experimental results and the corresponding performance which can be expected from this neutron source.
