In science fiction, an ion cannon is a beam weapon. It shoots beams of ions (atoms or molecules with an electrical charge). Because of its power, it is usually said to be a superweapon. An ion cannon is a type of particle cannon. The particles is shoots are ionized. Because of their electrical charges, they can cause electronic devices, vehicles, and anything else that has an electrical or similar power source to stop working. Ion cannons are used in many science-fiction movies and television series. Ion cannons are also used in many video games.

Real-world connections[change | edit source]

The science fiction idea for these weapons comes from the particle cannon created by Nikola Tesla. Tesla's cannon shot ions into the ionosphere. This caused them to be charged more. Research of this idea is still being done with directed-energy weapons.
