Un partenariat international au bénéfice de la science Grand projet européen, L'ILL voit le jour à Grenoble en 1967 sous l'impulsion de la France et de l'Allemagne, rejoints quelques années plus tard

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 ...

lables. We present here the calibration of a Guinier-Méring small angle X-ray camera. A molybdenum anode source, followed by a quartz monochromator, allows a monochromatic beam with high energy (E=17 keV ... prepared by simple mixing of a surfactant solution and a cosurfactant (octanol) has been observed. This striking process of self-organization ...

group studies the structure of a wide range of materials. Neutron diffraction instruments are used to provide detailed insights into the arrangement of atoms within a material, helping scientists to ... neutron scattering instruments are used to study a diversity of systems including biological materials, polymers, and colloids. The group is ...

fission products originating from a source of fissile isotopes placed in a beam tube (H9) near the core of the reactor. Specific fission products are selected by a combination of a magnetic and an electric sector ... there exists a thermal neutron interferometer (S18) which is operated as a CRG C instrument. FIPPS FIPPS is ILL's gamma-ray ...

type, the detector’s active area can range from a few cm² to several m², the spatial resolution from 1 mm and several cm, and the counting rate from a few Hz to several MHz. Design, calculation and project ... and visitors in a number of activities including data reduction, data analysis, instrument simulation and sample simulation. The production ...
