three different surfaces with crystal orientation [220], [111] and [113] respectively. The Bragg angle can be tuned from 27° to 55°. Typical usage: Interferometry The channel-cut monochromator offers a [220] ... double loop A typical interferogram at 30° Bragg angle is recorded in about 10 to 15 minutes. This time can increase considerably if the ...

A fast detection of phase transitions can also be obtained by scanning the temperature. A complete thermal variation of the diffraction patterns (1.5 - 300 K) can be achieved in few hours (3-5h). The texture ... magnetic structures. At small angles where magnetic peaks are expected, a high spatial resolution can be achieved, the FWHM reaches 0.25° ...

stresses in the Earth’s crust are stored, memorised in rocks. Reading it through neutron texture analysis can tell us much about geological mechanisms, for example subduction, which are involved in volcanoes and ... Neutrons are especially useful for studying rocks at the atomic scale. Being highly penetrating they can be used to investigate large ...

energy resolution by diffraction of gamma rays from perfect crystals, according to Bragg’s law. Both can operate with flat, nearly perfect Si or Ge crystals. In addition, a doubly bent crystal mode for GAMS5 ... interferometers. For this purpose the spectrometer crystals are mounted on interferometer arms. These can be rotated using a combined step ...

resolving powers up to A/ΔA =1500 can be reached as standard; energy resolution values E/ΔE are between 100 and 1000. A Reverse Energy Dispersion (RED) dipole magnet can be used to increase particle density ... separator, the fission product mass and kinetic energy Y ( A,E ) produced during thermal neutron fission can be investigated. The design ...
