Swing shift at LHC

Here we are again and nothing to do but sweep miles of floors. "I have a good idea, let's take anti-matter in one direction and matter in the other direction and ram them together at near c!" "Hey that could be cool, in the annihilation event energy it would create every more weird particles.", "Yes it could be the hit of the janitor's weekly astrophysics blog" "Or we could make a stream of alternating matter and anti-matter and time it so they reached the center of action at precisely the same time." "Okay here is a better one, protons and anti-protons rotating in a new type matter that is extremely dense and neutral." "Yes, like the shadow wire in that 'Ringworld' novel."
