Electron Diffraction Tube Manufacturer,Supplier and Exporter in Africa
Product Code : DA-AAN-11407
Quick Answer: 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.

About This Product
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. Didactic Africa can export the Electron Diffraction Tube to customers in Dominican Republic, Bulgaria, Seychelles, Bosnia and Herzegovina, Iceland and Mauritania.
Frequently Asked Questions
Q1. What does the Electron Diffraction Tube show?
The wave nature of electrons. Electrons passing through polycrystalline graphite form two concentric rings on a fluorescent screen, with a central spot from the undeflected beam.
Q2. How is the electron wavelength found?
It is calculated for various anode voltages from the radius of the diffracted rings and the distance between the crystal layers in the graphite.
Q3. What power supply does it need?
An EHT power supply. The maximum anode voltage is 5 kV and the maximum filament voltage is 6.3 V AC.
