Electromagnetic wave generator utilizing secondary electron multiplication

Abstract

The invention discloses an electromagnetic wave generator utilizing secondary electron multiplication. A slow wave structure or a resonant cavity is divided into two or three sections, and a secondaryelectron multiplication sheet is vertically inserted between the front section and the rear section. The secondary electron multiplier is provided with a plurality of micron-diameter micro-channels in the thickness direction; the inner wall of the micro-channel is coated with a secondary electron multiplication film; the height or the diameter of the micro-channel is far less than the thickness of the secondary electron multiplier, i.e., the length of the micro-channel; electrons collide on the inner wall of the micro-channel for multiple times, and dozens of secondary electrons are generatedin each collision; the secondary electrons are multiplied to realize electron beam current multiplication, namely energy multiplication, but density modulation generated by the electron beam is not influenced, so electromagnetic wave output with higher power and higher gain can be obtained. Meanwhile, a focusing magnetic field does not need to be additionally arranged; although only a small amount of electrons can hit the secondary electron multiplier after dispersion, the gain of the secondary electron multiplier reaches tens of thousands of times, so the electron beam current can be sufficiently amplified.

AI Technical Summary

Benefits of technology

The invention relates to reducing size without adding any extra magnets or increasing input energy by utilizing more powerful waves instead of just one type of light beam. This allows smaller generators that require less space than previous designs while still providing good performance.

Problems solved by technology

Technological Problem addressed by this patents relates to developing miniaturized electric devices called vacuums due to their ability to generate strong signals without requiring bulky components like cold cathode sources. Current methods involve adding extra parts to achieve these goals, making it difficult to produce them at large scales while maintaining good performance over time.
