It sounds horribly wrong to you? I'm going to actually devote time out of my day to looking up references now, thanks :/. All I know is it must be stored in some sort of a vacuum or something like that otherwise the gaseous particles of the air will collide with the positrons etc. and produce energy.

Ah, I was wrong. That's the tevatron. http://adcon.fnal.gov/userb/www/tevatron/

I guess that's where we get it from. It's stored in a magnetic bottle.
