Which e-beam gun do I need?
What are the main parts of an e-beam gun?
- E-beam Gun Emitter: E-beam emitters generate electrons emitted from a filament necessary for Electron Beam Gun Emitter Assemblies, Rebuild Kits & Parts | Thermionics material processing.
- E-beam Crucible Liner: E-beam gun crucible liners hold the material to be evaporated, ensuring material purity and preventing contamination.
- E-beam Gun Sweep Controller: E-beam gun sweep controllers manage the precise positioning and movement of the electron beam across the target material for uniform heating and deposition.
- E-beam Gun Filaments: The filaments serve as the source of emitted electrons formed into a beam by a split cathode assembly.
- E-beam Gun Solid State Power Supply: A critical e-beam accessory, the power supply provides the necessary energy to operate the e-beam gun with stable and consistent performance.
- E-beam Gun Magnets: The magnets focus the magnetic field and direct the electron beam accurately onto the target material.
What’s the difference between an e-beam gun and plasma or laser?
E-beam guns excel in precision evaporation and material processing, particularly in UHV settings, with a focused beam of high-energy electrons. Plasma and laser technologies rely on different energy delivery mechanisms, with lasers emitting light photons and plasma generating streams of charged particles.
