Proton beam cannon

Proton beams were powerful energy beams used in a variety of weapons.

The most famous of these were the planetary proton beams used as ammunition in superlasers such as the ones found on the Death Star I and Death Star II.

A smaller type of proton beam was used as ammunition for a gun monted on a modified Imperial-class Star Destroyer, the Accuser.
