Abstract
A high pressure, high resolution xenon x-ray detector array employs a housing having a window therein for passage of x-rays from an x-ray source and sealed to form a detection chamber. A voltage plate and a collector plate are disposed in the detection chamber in parallel relationship and passed through the housing to outside contacts. Xenon is disposed within the chamber with a pressure range of 50 to 200 atmospheres producing a xenon density in the range of 0.5 to 2.5 grams per cubic centimeter.
