electron gun

• Dispositif qui émet un flux d'électrons, généralement utilisé dans les tubes cathodiques, les microscopes électroniques et d'autres équipements scientifiques ou techniques pour créer des images ou contrôler des particules.

A device that emits a stream of electrons, typically used in cathode-ray tubes, electron microscopes, and other scientific or technical equipment to produce images or manipulate particles.
