Description
Introduced during World War II, this high-performance CRT found principal use in oscilloscopes and synchroscopes having wide bandwiths for pulse, radar and television measurements. The wide bandwith was achieved through neck deflection plate cap connections and their resultant lower capacitance. A post-deflection accelerator further eased deflection amplifier requirements while producing a bright trace for low repetition rate pulses. Bibliography: Peter A. Keller, 1991, The Cathode-Ray Tube.
