DENSS-multiple: A structure reconstruction method using contrast variation of small-angle neutron scattering based on the DENSS algorithm

BBA Advances, 2022
The 3D structure of biomacromolecules, such as protein and DNA/RNA, provide keys to understanding their biological functions. Among many structural biology techniques, small-angle scattering techniques with ab initio methods have been widely used to ...

Determination of the Axial-Vector Weak Coupling Constant with Ultracold Neutrons [PDF]

, 2010
A precise measurement of the neutron decay $\beta$-asymmetry $A_0$ has been carried out using polarized ultracold neutrons (UCN) from the pulsed spallation UCN source at the Los Alamos Neutron Science Center (LANSCE).

Two Pressure Cells for Quasielastic and Inelastic Neutron Scatterings [PDF]

EPJ Web of Conferences, 2022
Two clamp pressure cells for QENS and INS have been developed. One is a hybrid CuBe/NiCrAl cell which is for relative high pressure up to 2.5 GPa and another one is made from high strength aluminium alloy (mesolite NA723) with pressure up to 0.5 GPa. The

Ion source requirements for pulsed spallation neutron sources [PDF]

AIP Conference Proceedings, 1996
The neutron scattering community has endorsed the need for a high‐power (1 to 5 MW) accelerator‐driven source of neutrons for materials research. Properly configured, the accelerator could produce very short (sub‐microsecond) bursts of cold neutrons, said time structure offering advantages over the continuous flux from a reactor for a large class of ...

Rapid and efficient hydrogen clathrate hydrate formation in confined nanospace

Nature Communications, 2022
Clathrate hydrates are crystalline solids physically resembling ice, in which small molecules (typically gases) are trapped inside cages of hydrogen bonded, frozen water molecules.

The Spallation Neutron Source project [PDF]

Proceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 2003
The SNS is a "joint-venture" project of five DOE National Laboratories, aimed at building the world's most powerful accelerator-based pulse spallation source. At its planned 2 MW operation, it will produce neutron fluxes at least a factor of ten greater than Rutherford Appleton Laboratory's ISIS, currently the world's leading spallation source.
