Ion Canon

Ion cannons were a form of armament that fired ionized particles capable of disrupting electronic systems. Ion cannons fired particles that seriously interfered with the operation of electronics and computer systems, shorting circuits and often disabling them outright, in much the same manner as an electromagnetic pulse. The actual physical damage would sometimes result in fused joints on machines, due to the heat produced. Ion cannons could also slow down malfunctioning door shutters or otherwise disable shield generators.
Larger types could even disable a large capital ship, such as the Mega-ion cannons or planetary ion cannons. A more powerful form of the ion cannon, the massive ion pulse cannon was even more devastating but required the use of rare large formed Kyber Crystals to reach the required power levels.
Some believe the Galactic Empire is experimenting with ion cannons by modifying AT-ATs to become All Terrain Ion Cannons.
