Multi-Spectral X-Ray Detectors for Nondestructive Testing of 3D Printed Polymer Composites

The paper presents parameters of two multi-spectral X-ray detectors based on high resistivity chromiumcompensated gallium arsenide, which convert X-ray signal directly into electrical signal. Detectors consist of 80×80 and 256×256 pixels on 250 and 55 μm pitches, respectively. Their sensitive layer...

Description
Summary:The paper presents parameters of two multi-spectral X-ray detectors based on high resistivity chromiumcompensated gallium arsenide, which convert X-ray signal directly into electrical signal. Detectors consist of 80×80 and 256×256 pixels on 250 and 55 μm pitches, respectively. Their sensitive layer thickness ranges between 500 and 550 μm. At 3–4 keV photon energy, detectors offer high-quality X-ray images in the X-ray radiation range of 10 to 30 keV. Detectors allow distinguishing average densities between 0.3 and 2.4 g/cm 3 for 3D printed polymer composites.
