Quadcopter with payload

A quadcopter is a type of drone with four rotors, providing stability and agility in flight. It is widely used for aerial photography, surveillance, and recreational purposes. Quadcopters are maneuverable and easy to control, making them popular for both professional and hobbyist applications. They operate by adjusting the speed of each rotor to control direction and altitude. Their versatility and compact design make them suitable for various tasks, including search and rescue missions.

 

Electron Gun

 An electron gun is a device that emits a focused stream of electrons. Its primary function is to generate a controlled beam of electrons, typically for various applications such as cathode ray tubes (CRTs) in old television sets and computer monitors, electron microscopes, and other vacuum tube-based devices. The electron gun consists of a cathode, which emits electrons when heated, and an anode, which accelerates and focuses the emitted electrons into a beam. The controlled movement and intensity of this electron beam allow for the creation of images on a screen or the illumination of specimens in electron microscopy.
