Magnetic domains Instrument layout A vibration isolated optical bench provides support for two perfect silicon crystals. The first crystal, the monochromator, is located in a thermal beam line (H25) and directs ... S18 - Neutron interferometer The perfect crystal neutron interferometer is a Mach-Zehnder type interferometer for thermal neutrons. The ...

ThALES - Three Axis Low Energy Spectrometer The ThALES project is a collaboration between ILL and Charles University, Prague. Its construction was funded by the Czech Ministry of Science and Education

(jpg - 128 Ki) A general view of the instrument S18 is a dedicated neutron optics instrument. The perfect silicon-crystal interferometer and the detectors are mounted on an antivibration table.

neutron interferometers each one beeing designed for specific measurement purpose. These are cut from a large silicone single crystal.

becomes a superposition of "taking the left path" and "taking the right path" and finally interferes with itself. Therefore, neutron interferometry is a perfect tool to study the neutron as a quantum object ... The neutron behaves in front and behind the interferometer as a particle and inside purely as a wave. How interferometry works Perfect ...

the neutron. The reconstruction of the Wigner functions of various quantum states is made possible by a simultaneous measurement of the coherence function and of the modulated momentum distribution behind

path and spin degrees of freedom. Quantum entanglement With a similar experimental arrangement as for the previous example the entanglement in a single-neutron system of external and internal degrees of ... neutrons.

contextuality for the first time. Bell-like inequalities have been proven. Bell-theorem is a special case of a broader phenomenon called the Kochen-Specker theorem. An experimental test of the latter has

applications SALSA is the ILL stress imager dedicated to the determination of residual stresses in a broad range of applications in terms of components and materials. It is designed for diffraction me

General view of the instrument The instrument is shown with a turbine Ti blade mounted on the hexapod. The Delta Table and the slits are clearly visible. The beam flies from right to left into the two
