X-Ray Sensing Pickup Tube

Abstract
An X-ray sensing pickup tube free of white defects in the scanning area has been developed, and its characteristics have been evaluated. This pickup tube functions over a wide X-ray energy range, from 7 to 40 keV. The maximum spectral sensitivity, observed at a 20 keV photon energy, is 6×10-17 A/(photons/s). The limiting resolution is about 8µm. A preliminary study for monochromatic X-ray microradiography has also been performed.
