this is a weapon in EVE online, this is their description:

Particle blasters operate on a similar principle as the railgun except they fire a magnetically contained ball of subatomic particles. No other turret class can match the sheer destructive power of particle blasters, but due to the rapid dispersion of the containment field, it also has the worst range of all turrets. 

As for its actual damage and such I was just going to work on the assumption that it was essentially a very short range nuke that arrived at its target almost instantly. But [b]not[/b] so powerful that a frigate with a few antimatter shells would take down a capital ship, although several frigates and some lucky shots could cripple a capital.
