Meson Gun
Meson Guns create high energy mesons and direct them at targets. The collision of an electron and a positron creates a pi neutral meson. Mesons have short lives, which can be prolonged to precise duration by accelerating them to relativistic speeds. Range is set by varying the velocity of the mesons.
Mesons can pass through armor and matter without resistance. Mesons do not interact significantly with other particles, and matter is therefore transparent to them.
Mesons, however, decay in a short time into high-energy particles which do interact. If the point of decay is manipulated to occur inside the target ship, the result is high energy explosions and radiation damage. In a meson beam, the mesons travel to its target where they decay and release a large amount of energy.
