electron-beam plasma

Electron-beam plasma is a type of plasma created by using a focused stream of high-energy electrons—called an electron beam—that interacts with a gas or material. When the electron beam passes through, it ionizes the atoms, stripping away electrons and creating a mixture of free electrons and positive ions. This process generates plasma, which is an energized, conductive state of matter often used in materials processing, scientific experiments, and advanced manufacturing. The electron beam provides precise control over the plasma's properties, making it useful for applications like surface treatment and thin-film deposition.
