AVS offers under license a Precision Attenuator for Hard X-Rays (ABS-300) developed over many years at the PETRA III light source at DESY (Hamburg). This system provides the ability for scientists to reduce the incident x-ray flux to any desired value.
The ABS-300 precision attenuator is of the filter bank rather than wheel type. This High Vacuum X-Ray Attenuator contains 12 frames which carry the attenuation foils. Each of these frames moves on a ball-bearing slideway assembly. The motion is actuated by pneumatic pistons outside the vacuum which move the frames using a magnetic field through the chamber floor. This means that no vacuum feed-through is used for this design and that the absorber moves promptly and quickly. The pneumatic pistons are controlled by a manifold of electric valves which controlled from a Windows PC using the provided electrical controller.
