electron gun (n)
the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
electron gun Sentence Examples
- The electron gun within the cathode-ray tube (CRT) monitor fired electrons at the phosphor-coated screen to produce images.
- The electron gun of a scanning microscope sweeps a focused beam of electrons across a sample to create magnified images.
- The scanning electron microscope (SEM) utilizes an electron gun to scan the surface of a sample with a focused beam of electrons.
- In a transmission electron microscope (TEM), an electron gun accelerates electrons through a condenser lens and onto a thin sample, allowing for high-resolution imaging of the sample's internal structure.
- Electron guns are also used in electron beam welding (EBW) to generate a precisely focused beam of electrons for welding metals and other materials.
- Electron guns are essential components of X-ray tubes, where they direct a beam of electrons onto a metal target, releasing X-rays through the process of bremsstrahlung.
- High-power electron guns are used in particle accelerators to accelerate charged particles to very high energies for research and applications in nuclear physics.
- Electron guns are crucial in free-electron lasers (FELs) to generate intense beams of coherent light across a wide spectrum by oscillating electrons through periodic magnetic fields.
- Electron guns are used in analytical instruments such as electron microprobes to analyze the elemental composition of materials by focusing an electron beam on a sample and detecting the emitted X-rays.
- Electron guns play a vital role in electron beam lithography, where they precisely direct a beam of electrons onto a resist-coated substrate to create intricate patterns for microelectronics fabrication.
