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.

On the role of secondary pions in spallation targets [PDF]
, 2016 We use particle-transport simulations to show that secondary pions play a crucial role for the development of the hadronic cascade and therefore for the production of neutrons and photons from thick spallation targets.

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.
