Generating a Pulsed Electron Beam using Microwave and Pulsed RF-based Guns in EMs

Generating a pulsed electron beam using microwave and pulsed RF-based guns in EMs is similar to RF-cavity chopping, but the electron beam is directly generated in microwave or RF-based electron guns. These guns modulate electron generation using an RF electric field, producing pulsed electron bunches. 

The key features of generating a pulsed electron beam using microwave and pulsed RF-based guns are:

  • Generates highly collimated and focused pulsed electron beams.
  • Often used in high-energy applications like electron beam lithography or particle accelerators, though adaptations exist for EM.

This technique can be used in high-energy pulsed electron applications and advanced EM techniques.
