<p>in order to achieve a high resolution in an X-ray analysis apparatus, use is made of a monochromator comprising four crystals which are pair-wise positioned in parallel orientation, the two pairs being positioned in a mutual anti-parallel orientation. In order to achieve a high beam intensity, the radiation source may be arranged in the immediate vicinity of the first crystal pair. Each of the crystal pairs is preferably cut so as to form a U-shape from a single block of monocrystalline material relatively free from dislocations, preferably germanium.</p> |
