Nuclear Physics and Energy Questions

Multiple choice

What is the primary mechanism responsible for the generation of plasma in a capacitively coupled plasma reactor?

  1. Radio-frequency heating

  2. Microwave heating

  3. Laser-induced breakdown

  4. Electron-beam bombardment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In a capacitively coupled plasma reactor, radio-frequency energy is applied to a pair of electrodes, which generates an electric field. This electric field accelerates electrons in the plasma, which collide with other particles and generate more electrons and ions, sustaining the plasma.
