Abstract
The present invention relates to the manufacture of ionization detectors used in X-ray tomographic imaging. One form of the invention discusses a method of manufacturing an array of ionization detectors which reduces spurious electric currents in the detectors when the detector spacing is in the 1.5 mil range. Also discussed is a method of manufacture of a chamber for containing an ionizable gas such as xenon, and of sealing the detector array at its point of entry into the chamber in order to prevent the escape of xenon.
