ABSTRACT:
In an x-ray detector of the type employing a gas-filled chamber containing a number of electrode plates for detecting ionization event caused by the interaction of x-ray photons with the gas, a number of detector cells are formed, each detector cell containing two electrode plates disposed in a plane in succession in the direction of propagation of an incoming x-ray beam. In order to permit the acquisition of different spectral ranges, the electrical signals from the electrode plates are respectively conducted out of the chamber. The electrode plates are plugged into spring contacts and are connected group-by-group to a conductor foil. Each conductor run within the conductor foil has a contact projection for making electrical contact between the conductor foil and a printed circuit board, which carries electronic components for processing the detector singles.
