Principle

Laue diagrams are produced when monocrystals are irradiated with
polychromatic X-rays. This method is primarily used for the
determination of crystal symmetries and the orientation of
crystals. When a LiF monocrystal is irradiated with polychromatic
X-rays, a characteristic diffraction pattern results. This pattern
is photographed with the digital X-ray sensor XRIS.

Tasks


The Laue diffraction of an LiF monocrystal is to be recorded
with the aid of the digital X-ray sensor.

The Miller indices of the corresponding crystal surfaces are to
be assigned to the Laue reflections.
