Abstract
A multicell x-ray detector of the gas-filled ionization type includes a metal body in which the front, rear, end and bottom walls together with a sealed cover define a channel in which there is a row of spaced apart electrode plates which define cells in which ionization events and resultant analog signals are produced in response to absorption of x-ray photons by the gas. The x-ray entrance window is formed in the front wall and extends over substantially the length of the channel. The window has a curved cross section which permits restriction of its internal stresses to tensile stresses so its thickness and, hence, its x-ray absorption is minimized. The edges of the electrode plates which are presented toward the window are curved to be concentric with and slightly spaced from the window.
