Teltron Tube - Electron Diffraction Manufacturer,Supplier and Exporter in India
Product Code : EL-AS-10813
Product Description
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.
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.
Study of the ring pattern and it's variation with different anode voltages permits the study and verification of the de Broglie's hypothesis, shows the dual nature of the electron, permits the calculation of the spacing of diffracting planes and suggests the probable arrangement of carbon atoms.
The tube uses an electron gun with an indirectly heated cathode to project a narrow converging beam of electrons through a thin layer of graphitised carbon supported on a fine mesh grid over the exit aperture of the gun.
The cathode rays are diffracted in passing through the carbon layer and produce a ring pattern on the phosphor coated end of the tube.
