TARGET AND TARGET ASSEMBLY FOR A CAMERA TUBE AND METHOD OF MANUFACTURING SAME

摘要

A target and target assembly in which a semiconductor plate is provided on an annular support. According to the invention the target consists of a semiconductor monocrystalline edge portion which comprises an integrated circuit for handling the electrical signals originating from the target, the central part consisting of a radiation-sensitive layer having one or more radiation-permeable electrodes. The electrodes are connected to inputs of, the integrated circuit of which the leads necessary for supply and control voltages are led through. A window is provided on the electrodes and overlaps the inner edge of the support. The window, the said edge portion and the support adjoin each other in a vacuum-tight manner; the assembly can be connected directly on the camera tube.
