ABSTRACT:
A metal layer deposited on a wafer opposite to the photocathode is brought to a potential which is at least equal to that of the photocathode. The wafer layer and screen layer form conductors for a biplanar wave-propagation line element having a characteristic impedance equal to that of an external propagation line. The shutter tube is provided with matched means for connecting the line element to the external line, a voltage signal being applied to the line element so that the screen layer is brought progressively to a higher potential than that of the wafer layer.
