Beam days lost per cycle on ILL & CRG instruments (≈1600 to 2600 days allocated per cycle) Beam days lost per cycle on ILL public instruments (+1000 days allocated per cycle)

components of the beam conditioning part are the two background choppers, the double curvature mono-chromator with four faces and the Fermi chopper. The background choppers are rapidly pulsating beam shutters which ...

monochromator using a single reflection via a highly oriented pyrolytic graphite (HOPG) crystal provides a beam at a fixed take-off angle with a wavelength of 2.4 Å. MoTo was designed for long experiments with ... contrast options to measure independently of NeXT. Access to the hutch is possible only when the NeXT beam is off, and needs to be ...

prototype in December 2017 at the LLB on the G4.3 instrument. Two beam conditions were used: a narrow beam of 3 mm x 3mm, or a non collimated beam with a plexi attenuator to avoid signal saturation. The detection ... detection efficiency measured at 2.8 Å with the narrow beam centered in the middle of the cells was 51% with the standard grid, and ...

r is extremely simple. When a single crystal is placed in a white beam it diffracts neutrons in many directions. The diffracted beams which hit the detector surface produce so called Bragg dots of varying
