Wide-Angle X-ray Scattering (WAXS)

As a technique that is complementary to SAXS, WAXS extends the length scale at which a sample can be investigated – down to interatomic distances. Performed either simultaneously or interchangeably with SAXS, this approach carries strict demands for an X-ray detector. Ideally, the same system should fulfill the needs of both techniques; it should offer noise-free performance, a high dynamic range, stable measurements, and extremely short readouts.

This challenge was met by photon-counting detectors: with their count rate of 1e⁷ photons/s/pixel and cosmic background of 0.1 counts/h/pixel, they achieve a dynamic range of above 1e¹¹. While these features certainly benefit static experiments, the quantum efficiency and readout time allow researchers to investigate dynamic or in-situ processes as well. Extra features include vacuum compatibility and an option to have custom-made detectors designed.

• ✓ A high dynamic range captures SAXS and WAXS signals, either simultaneously or interchangeably.
• ✓ Our wide detector portfolio satisfies any experimental geometry.
• ✓ Our detectors offer stable calibration files and stable operation.
