Specification:
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 on a fluorescent screen.
EHT Power Supply
Digital Meter with two shunts included
Also intended for determining the wavelength as a function of the anode
voltage from the radius of the diffraction rings and the lattice plane
spacing of graphite, as well as confirming
de Broglie’s hypothesis. Instructions included
Max. anode voltage: 5 kV
Anode current: approx. 0.1 mA at 4 kV
Max. filament voltage: 6.3 V AC
Lattice constant of graphite: d10 = 0.213 nm; d11 = 0.123 nm.
