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

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

The detector The position sensitive neutron detector (PSD) is a set of 3He tubes. The assembly can be moved inside the detector tank to adjust the instrument resolution. When the photo was taken, not

The sample chamber The sample can be placed either in sample chamber (opposite) under vacuum and at low temperature or in a furnace.

The monochromator BRISP offers the choice between 3 large monochromators made of a set of carefully aligned single crystals of graphite or copper.
