The KWS-1 small-angle neutron scattering (SANS) instrument operated by the Jülich Centre for Neutron Science (JCNS) at research reactor FRM II of Heinz Maier-Leibnitz Zentrum in Garching near Munich has been recently upgraded. was updated, from its active collimation apertures to detector cabling. Most parts were installed first time, including a broadband polarizer, large-cross-section radio-frequency spin flipper, chopper and lenses. A custom-designed hexapod sample position allows heavy...
An overview is provided of the 15 neutron beam instruments making up initial instrument suite European Spallation Source (ESS), and being made available to user community. The ESS source consists a high-power accelerator target station, providing unique long-pulse time structure slow neutrons. design considerations behind structure, moderator geometry layout are presented. 15-instrument two small-angle instruments, reflectometers, an imaging beamline, single-crystal diffractometers; one for...

Aspherical neutron lenses are discussed in detail as focusing elements for existing small-angle scattering (SANS) diffractometers. The conceptual design can be obtained by analytical equations, while computer simulations provide the intensity distribution of primary beam, which is strongly correlated with instrumental resolution and minimal momentum transfer Q . For large illuminated sample/lens areas 50 mm diameter aspherical lens essential, spherical limited to ca 20 a 60% aberration...
Following demand from the user community regarding possibility of improving experimental resolution, dedicated high-intensity/extended Q-range SANS diffractometer KWS-2 Jülich Centre for Neutron Science at Heinz Maier-Leibnitz Center in Garching was equipped with a double-disc chopper variable opening slit window and time-of-flight (TOF) data acquisition option. The used concert high-intensity velocity selector enables tuning will wavelength resolution Δλ/λ within broad range, 20% (standard)...
The High Brilliance neutron Source (HBS) is a project for next generation research facility, based on new concepts and recent technological advancements. As elementary processes it uses neither fission nor spallation, but instead low energy nuclear reactions in very compact Target-ModeratorReflector (TMR) assembly. Our facility design results efficient production of beams with high brightness. Key features HBS are: (i) competitive instrument performance, (ii) comparatively construction...
Small-K Advanced DIffractometer (SKADI is a Small-Angle Neutron Scattering (SANS) instrument to be constructed at the European Spallation Source (ESS). SANS instruments allow investigations of structure materials in size regime between Angstroms up micrometers. As very versatile instruments, they usually cater scientific needs communities, such as chemists, biologists, and physicists, ranging from material food sciences archeology. They can offer analysis micro- mesoscopic samples, well an...
High Current Accelerator driven Neutron Sources (HiCANS) are a cost-efficient alternative for future large scale neutron facilities. They excel in transforming neutrons released by the primary nuclear reaction into spectral range usable applications. In particular, cost of target station represents only minor fraction overall construction due to lower energy neutrons, which requires less shielding. can be designed provide optimized pulse and properties applications scattering, analytics...
