Anti-proton is sling weapon from what I can tell. You have the anti-mater particle stripped of positron in cloud. You then shoot electron current past it swaying the normal atomic cloud to reach a different set of quanta emmissons needed for the phase modulation. It's got to involve anti-mater on board making it more dicey, if it picked up a positronic charge the thing could detonate. Odd. Data runs on positronic calculation so... He's not really going to be ideal on handling one on the away team.... Or rather more hazardous.
