The photoelectron throughput in streak tubes may be understood by using the brightness theorem to couple the photoelectron emission from the virtual cathode, through the anode aperture, to the recording screen. The virtual cathode is generated by the immersion lens formed by the photocathode-accelerating electrode structure. The throughput is limited by the anode aperture that acts as a system field stop. The authors have calculated the throughput for a variety of streak tubes, given the photoelectron energy distribution of some typical photocathodes. They conclude that higher throughputs are obtained when using a slot, rather than a mesh, for the accelerating electrode. The variable magnification design of the Philips P850 streak tube allows one to optimize the throughput for arbitrary photoelectron energy distribution. This work was done to support inertial confinement studies.
