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:7,0 V AC/DC
- Anode voltage: 0 - 5000 V DC
- Anode current: typ. 0,15 mA at 4000 V DC
- Lattice constant of graphite: d10 = 0.213 nm; d11 = 0.123 nm
- Distance from graphite target to fluorescent screen: 125 +/- 2 mm approx.
- Fluorescent screen: 100 mm dia. approx.
- Glass bulb: 130 mm dia. approx.
- Total length: 260 mm dia. approx.
