ABSTRACT:
A stripline is composed of a microchannel plate, and a gold transmission path and grounded electrode formed on both surfaces of the microchannel plate. X-ray images projected onto the transmission path is gated by a pulse voltage applied to and propagating through the stripline. The stripline has such a characteristic impedance profile as decreases toward its output end. This impedance profile compensates for a voltage drop due to the transmission loss which would otherwise appear.
