Secondary emission refers to the phenomenon where primary energetic particles (such as electrons or photons) strike a material and cause the ejection of additional particles from that material. This process is common in various fields, including physics, materials science, and engineering. Here’s a brief breakdown of how secondary emission works: 1. **Primary Energy Input:** An incoming particle (like a high-energy electron or photon) impacts the surface of a material.
