Demonstration Electron Diffraction Tube
Demonstration Electron Diffraction Tube
TEL-555
The 555 Demonstration tube is the same tube we have offered for more than 30 years. It is offered primarily for departments that have a pre-existing collection of tubes and bases, and would like a replacement tube. Both the 555 and the 2555 are built to the same high standards and will serve as a valuable educational tool for years to come.

Highly evacuated electron tube for demonstrating the wave nature of electrons through the observation of interference caused by passage of electrons through a polycrystalline graphite lattice (Debye-Scherrer diffraction) and rendered visible a fluorescent screen. Also intended for determining the wavelength as a function of the anode voltage from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.
Specifications:
Max. filament voltage: 6.3 V AC
Max. anode voltage: 5 kV
Anode current: approx. 0.1 mA at 4 kV
Lattice constant of graphite: d10 = 0.213 nm; d11 = 0.123 nm

With the Electron Diffraction Tube one can verify the de Broglie hypothesis and establish the dual nature of the electron. In addition, one can calculate the interatomic spacings of carbon, (the diffracting material in the tube). (Cables are not included in the system.)
Also available is the same system but with the MCP power supply.
