Test detector station

This station is equipped with a Nonius-Bruker FR591, 5 kW Cu Rotating Anode source (Emission Energies: Kα1 = 8.048 KeV, Kα2 = 8.028 KeV), and is mainly used for detector testing.
Its main components are the source and a Huber Graphite-Monochromator, optimized for 8 keV.
A PC is used for controlling shutters and source powering.
The station has a cabinet with plexiglass windows aimed at containing the monochromatic 8 keV X-Rays emission.


Huber Graphite-Monochromator 151

The Graphite-Monochromator 151 contains a highly oriented pyrolytic graphite crystal (HOPG) mounted in a compact metal housing.
Inside the radiation-proof housing the crystal can be manually adjusted to the ideal Bragg-angle for the used X-ray wave length. The diffracted beam is made directly visible by a fluorescent screen on a small lead glass window.
Adjustable entry and exit slits ensure a precise limitation of the X-ray beam path.
