The 14 pages that link to Electron gun, each with the reason it gives.

• Electron microscopyRelated: The electron source sets beam brightness and contributes to attainable resolution.

• Cathode-ray tubeBroader topic: Its cathode and electrodes generate the beam that forms the image.

• Electron microscopeRelated: It supplies the beam that illuminates or scans the specimen.

• Transmission electron microscopyRelated: The gun supplies the beam that illuminates the specimen.

• Thermionic emissionRelated: Thermionic cathodes are a common source for its beam.

• Scanning electron microscopyRelated: It supplies the beam that the microscope focuses and scans across the specimen.

• Davisson–Germer experimentBroader topic: The gun set the beam’s kinetic energy, and therefore its de Broglie wavelength.

• Scanning electron microscopeRelated: It supplies the electrons that the microscope focuses onto the specimen.

• Clinton DavissonRelated: A controlled electron beam was necessary to measure scattering from the crystal.

• Lester GermerRelated: A controlled electron beam supplied the particles scattered in the Bell Labs measurements.

• Kenjiro TakayanagiBroader topic: The cathode-ray receiver formed its visible image with a controlled electron beam.

• Beam techniquesRelated: It creates the electron stream used in many beam instruments.

• Owen RichardsonRelated: Many electron guns begin with a thermionic cathode whose current follows Richardson’s law.

• Vacuum electronicsRelated: Electron guns provide controlled beams in tubes such as klystrons and traveling-wave tubes.
