KT-KC
Knudsen effusion cell
Knudsen effusion cells in low-, standard-, and high-temperature variants. Each range uses a dedicated filament and heat-shield stack to keep the flux stable and limit chamber-wall heating.
Features
- Rated for UHV
- PBN, Al₂O₃, or W crucibles
- Water-cooled sleeve
- Manual or motorized shutter
- Optional programmed control
