Ion cannon
In the Star Wars universe, Ion weapons are common. They range from handheld pistols to star ship cannons. Ion weapons are mainly used to stop electronic systems from working. They can stop vehicles, droids and starships without doing any damage. In Star Wars Episode V: The Empire Strikes Back, the Rebel Alliance uses a large ion cannon on the planet Hoth to disable Imperial Star Destroyers near the planet. This is done to stop them from firing on Rebel ships trying to leave the planet. The Jawas used ion blasters to disable R2-D2.
