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
