of a straight then curved vertical neutron guide which selects very cold neutrons (VCN) with a speed of only 60 m/s. Then, these neutrons enter a "neutron turbine" and hit blades rotating with a receding ... of about 25 m/s. This transforms neutrons into UCNs with a velocity range from 0 to 15 m/s. The VCNs and UCNs produced by PF2 are distributed ...

important to establish reliable and standard codes of practise. A key part of standard development is the measurement of round-robin samples. A ferritic steel weld (see figure 1) was prepared and was measured ... and is now a full international standard. Ref.: Residual stress distributions in welded ferritic steel T-plate joints .

The red line is the result of a linear combination of the simulation (blue dots connected by a solid line) and multiple scattering (green dashes) data to the experimental ... microscopic behaviour. For this reason, after a thorough experimental, computational and theoretical scrutiny, the dynamics of ...

formation of a cyclic water hexamer in zeolite NaX Neutron powder diffraction is a valuable tool for the study of hydrogen and water molecules in materials. This is demonstrated here with a study of the ... the adsorption of water on zeolites which is a subject of great scientific and technological interest due to the broad spectrum of zeolite ...

by Anton Oed in the late 1980s. Anton Oed passed away on 30 September 2018; he was a passionate inventor and remains a source of inspiration for many of us today. The ILL would therefore like to honour ... encouraging the development of detector techniques for scientific applications. The Anton Oed Prize, of a lump sum of 1000 €, was awarded on ...

Checking a disk chopper before installation The disk of one of the 6 choppers IN5 choppers are large (Ø 75 or 69 cm) and thin disks (50 to 1 mm) coated with gadolinium oxide (Gd 2 O 3 ) rotating at high

neutron-scattering from SiO 2 precipitates in a single crystal of silicon which has been heat treated for 500 hours at 600°C; the neutron beam was incident along a <100> direction. The central cross arises

The detector tank D11 with its new colors after its upgrade with a larger and faster detector, new collimating guides, etc. This photo makes it possible to assess the length of the detector tank.
