The Plasma Beam is available after research is completed on either the Heavy Plasma squad weapon and the Heavy Plasma Clip, or on the standard Plasma Rifle and Plasma Rifle Clip. As a research topic it is called the "Plasma Cannon".
This weapon is widely regarded as the best craft weapon available to Commanders. With a fantastic range that allows interception craft to engage all UFOs (with the exception of Battleships) without fear of being fired upon, a huge number of shots per charge and a superb reload time, the Plasma Beam should be fitted to all interception craft as soon as possible.
It is worth noting however that an interception craft armed with dual Plasma Beams is capable of completely destroying the smaller UFOs. If you wish to salvage artefacts and resources from these smaller UFOs it may be worthwhile keeping at least one Interceptor available with weaker weaponry such as Stingray missiles.
Note that unlike the Fusion Ball Launcher, using Plasma Beams does not require your engineers to manufacture ammunition - the Plasma units recharge automatically upon return to base.
