Flat deflection system for a channel multiplier CRT

It has been established that large-area channel electron multipliers can be used in cathode-ray tubes to separate the scanning and light generating functions within the tube. The resulting low-voltage scanning beam can be utilised to make a thin deflection system. The paper describes the mode of operation of this deflection system, accompanied by photographs which illustrate the performance. Brief mention will also be made of plans to make sealed-off tubes with a 12 in picture diagonal that will be 75 mm thick and have a power consumption of about 5 W.
