Electron Diffraction Tube Electron Diffraction Tube
The electron diffraction tube is highly evacuated tube with an electron gun consisting of pure tungsten heater filament and cylindrical anode all contained in clear glass bulb. The electrons emitted by the heated cathode are constrained to narrow beam by an aperture and are then focussed by means of an electron-optical system. The resulting tight, monochromatic beam then passes through micro-mesh nickel grating situated at the aperture of the gun. Onto this grid, thin layer of polycrystalline graphitised carbon has been deposited by vaporisation. This layer affects the electrons in the beam much like diffraction grating. The result of this diffraction is seen in the form of an image comprising two concentric rings that become visible on the fluorescent screen. spot resulting from the un-deflected electron beam continues to be visible at the centre of the rings. Also requires an EHT power supply.
Specifications:
• Max. filament voltage: 6.3 V AC
• Max. anode voltage: 5 kV
• Anode current: approx. 0.1 mA at 4 kV
