Space Charge Wave

A vacuum tube using the velocity-jump principle was built to amplify microwave frequencies in the vicinity of 10,000 Mc./s. The design of the tube was based on a similar structure that had been built to operate at a lower frequency. A general theory previously developed for space-charge wave amplifiers was applied to the operation of the tube, in conjunction with approximations made to the theory of coupling to electron beams by means of helices. The experimentally measured gain was in moderate agreement with that predicted by this theoretical development. Conclusions are drawn regarding the operation of coupling helices, and the effect of small gaps in the amplifying section of the tube.
