E-Gun
Field emission based digital electron gun using carbon nanotube emitter
Product Catalog
We have a wide range of product line by developing our own technology for cold cathode type electron gun with carbon nanotube emitter and hot cathode type electron gun with filament.
CAT Beam Tech's carbon nanotube electron gun has self-focusing structure with less than 15% gate leakage loss when operated in triode mode.
Features
• Low Leakage Ratio ( <1% )
• Multi-array configuration
• Focusing electrode control function ( <0.1mm )
• Customized production
