摘要:

Velocity modulation of an electron beam, which is the underlying physical phenomena for various microwave tubes such as klystrons and magnetrons, is interpreted in terms of a water bag model which has its origin in plasma physics. Using this technique, it is possible to estimate the expected amplitude for a velocity‐modulated electron beam.
