Meson Cannon
The Meson Cannon first deployed on the GTD Golgotha is a massive and extremely powerful weapons, far more so than any previous GTVA weapon. The key to the prodigious damage output of this weapons is the use of mesons, strongly interacting elementary particles midway in mass between leptons (electrons and the like) and baryons. (protons, neutrons, etc) While in principle, the Meson Cannon is similar to a GTVA-standard particle beam cannon in that a linear accelerator is used to propel charged particles to relativistic speeds, instead of typical proton or deuterium beam mass, the Meson Cannon uses mesons, which results in a significantly different end result. The advantage mesons have over baryons from a weapon designer standpoint is that they interact not with the electromagnetic bonds holding matter together, but instead the strong nuclear force, which binds the nucleons of an atom together. The effect of massive irradiation of relativstic mesons upon a target has the result of essentially disintigrating it at the nucleon level, bypassing any defenses against standard weapons such as heat dispersing grids and ablative armor.
Note: All meson-based technolgy is very dangerous and potentially lethal in case of containment field breach. Targets hit by meson-based weaponry are highly radioactive due to secondary effects resulting from atomic disruption. Only wear class-5 or better radiation gear when dealing with meson-irradiated materiels.
