Simulated experiment The thermal neutron beam from the reactor is divided into two parallel beams, one for D2B, the other for D20. The D20 beam first reaches one of its four monochromators. The monochromatic ... It then reaches the sample (usually a cylinder of powder in a furnace or in a cryostat) which diffracts it in many directions. The ...

Neutron scattering on undercooled metallic melts This movie was shot on D20 in october 2000. The target of this experiment was diffraction studies of supercooled melts of metals or metal alloys. Here the

restoration? Can fracture healing be accelerated? Etc. These questions can be adressed through neutrondiffraction experiments on D20 as shown here with a sheep bone study. Ref .: Benmarouane A. , Hansen T
