A Matrix Gallium-Arsenide Detector for Roentgenography

A matrix gallium-arsenide detector for roentgenography and nondestructive monitoring is described in this work. The detector contains 128 × 128 sensitive elements with 50-μm pitch, an analog multiplexor, and a system for information acquisition. The detector is intended for use in low- or medium-dose medical X-ray apparatuses. It can also be used for nondestructive defectoscopy.
