Electron Diffraction Tube
DDAFRICA-001-0164
The Electron Diffraction Tube illustrates the wave nature of electrons: a beam passing through a polycrystalline graphite target produces two concentric rings on a fluorescent screen. It works at anode voltages up to 5 kV and needs an EHT power supply.
Electrons from the heated cathode are formed into a tight beam and sent through a thin graphite layer that behaves much like a diffraction grating. The resulting rings appear on the fluorescent screen around a central spot from the undeflected beam. From the ring radius at different anode voltages and the spacing between the crystal layers in graphite, students can calculate the electron wavelength.
Key Features
- Electron gun with pure tungsten heater filament and cylindrical anode
- Beam narrowed by an aperture and focused by an electron-optical system
- Micro-mesh nickel grating coated with polycrystalline graphitised carbon
- Two concentric rings with a central undeflected spot on the screen
- Highly evacuated clear glass bulb
- Requires an EHT power supply
