The technique of the high-speed cathode-ray oscillograph

After an introduction in which the need for high-speed oscillography and the nature of the problems are explained, an equipment built for recording the ¿uncontrolled¿ surges of a 1 000 000-volt impulse generator is described. Attention is concentrated on the problems of discharge tubes, beam traps, sweep circuits, and screening. Examples of the oscillograms obtained are given.
