A short manual for the use of D22 This document is under construction. It will describe how to set up D22 and give a short reminder of important commands. There will also be help about emergency procedures

Flux measurements with a calibrated monitor at the sample position for the upgraded IN12 in comparison to the former instrument. A general view of IN12 Flux measurements with a calibrated monitor at the

D22 - a small-angle neutron scattering diffractometer Small-angle neutron scattering (SANS) is a technique that measures the deviation at small angles (much less than one degree to several degrees) of ... of a neutron beam due to structures of small size in the sample. "Small" means dimensions of a few tenths to about 100 nanometres, such as ...

. Research with neutrons: a collective effort! Excellence The ILL is the most intense source of neutrons in the world. This enables us to publish over 140 scientific papers a year in the world's most ... knowledge Science strives to augment human knowledge, which, as we understand it, is a universal gift to be used to make this world a better ...

overlap ratio. As an example, a wavelength of 5 Å and a chopper velocity of 8500rpm give a resolution of 100 µeV with a frame overlap ratio of 3 (as we are close from the boundary a ratio of 2 might be also ... 8500 rpm, i.e. half the maximal velocity, for a frame overlap ratio of 1 (same velocity for all the choppers). Doubling this velocity leads ...

wavelength neutrons for lower resolution of larger structures. Usually a large composite monochromator, up to 300 mm high, is used to select a narrow band of wavelengths and focus it onto the sample.The monochromator ... and linear position-sensitive detectors (PSDs) cover a large solid angle for maximum efficiency. The two high-resolution powder ...

The ILL was founded in Grenoble in 1967 by France and Germany, joined a few years later by the UK. These are ILL's three Associate Countries. Today, 10 additional Scientific Member countries fund the ILL
