Laue diffraction

Ever observed a fighter jet at its most agile, flying curves impossibly tight, accelerating and decelerating so fast it makes your head spin? Such maneuvers require extremely powerful engines, delivering a lot of power in no time at all.  Deep inside those engines, you can find special turbine blades spinning in truly hellish conditions. Temperatures can reach into thousands of degree Celsius, and the force tearing at those blades is equivalent to the weight of a large truck. A class of materials that can withstand such forces are single crystal alloys. Small defects in the crystalline structure of these alloys can weaken the stability of the material. Thus, manufacturers regularly inspect such turbine blades for crystalline defects using Laue diffraction.

Hybrid Photon Counting detectors speed up such tests by an order of magnitude in any diffractometer geometry: side-reflection, back-reflection and transmission. In HPC detectors, each pixel is its own detector equipped with a dedicated threshold to reject noise and low energy X-rays. HPC detectors acquire images noise free, with unlimited dynamic range and a single-pixel point spread function.

These properties give the detector an unmatched signal-to-noise performance. Especially in transmission geometry, when much of the X-rays are absorbed in the dense and thick alloys, signal-to-noise performance is a real issue. It was shown that using HPC detectors, quality test images can be generated using 5x less X-ray signal compared to conventional, integrating detectors. Tests can thus be done much faster and for thicker samples.
