Simulated experiment A principle of a neutron Laue diffractometer is extremely simple. When a single crystal is placed in a white beam it diffracts neutrons in many directions. The diffracted beams wh

How fast is CYCLOPS ? This movie was recorded during the very first tests of the instrument in June 2009. It shows that exposures as short as a few seconds are enough to get excellent Laue patterns fr

(png - 111 Ki) First tests. The figure shows the raw stitched Laue pattern (a) obtained with a ruby crystal in 20s of acquisition time. Figures (b) and (c) are the transformed to cylindrical geometry

Principle of the spin-echo technique Spin-echo spectrometers are based on the determination of neutron velocities by using the Larmor precession of their spin in a constant magnetic field. This is a t

Simulated experiment SuperADAM operates as a fixed wavelength neutron reflectometer The neutron beam from the cold neutron guide H521 arrives at the monochromator which selects a narrow wavelength ban

Pedagogical animations Six animations are shown : without phase shifter (-> no contrast) normal with absorber with spin flipper, vertical analyzer (-> no contrast) with spin flipper, horizontal analyz

Texture of subduction rocks The history of strain and stresses in the Earth’s crust are stored, memorised in rocks. Reading it through neutron texture analysis can tell us much about geological mechan

Why can’t alkaline batteries be recharged? D1B is a high intensity powder diffractometer with an 80° PSD (position sensitive detector). One of its major use is for kinetic and real time experiments li
