KSCI-DFTS Klinger Scientific Diffraction Tube S
Klinger Scientific Diffraction Tube S Experiment Topics: .. The following topics can be discussed with this highly evacuated tube: • Illustration of the wave nature of electrons• Determination of the wavelength of electrons depending on the anode voltage• Debye-Scherrer diffraction• Confirmation of the de Broglie hypothesis Product Information: .. The electron diffraction tube is a highly evacuated tube with an electron gun consisting of a pure tungsten heater filament and a cylindrical anode all contained in a clear glass bulb. The electrons emitted by the heated cathode are constrained to a narrow beam by an aperture and are then focussed by means of an electron-optical system. The resulting tight, monochromatic beam then passes through a micro-mesh nickel grating situated at the aperture of the gun. Onto this grid, a thin layer of polycrystalline graphitised carbon has been deposited by vaporisation. This layer affects the electrons in the beam much like a diffr
