I'd say relatively little of your taxes went to this if you're in the US. I'm not sure of the international participation on this experiment, but I'd expect there's some contribution from other countries as well. Most big experiments like this have international participation and at least some international funding. Of course, there are other big experiments drawing other taxes from a variety of nations. But it's pretty small compared to other things, and particle physics, besides being very cool on its own, has plenty of ancillary benefits (like the web).
If you haven't seen anything about how the big magnet in this experiment moved from Long Island to the Chicago suburbs, it was something else. Here's some on it: Fermilab | Muon g-2 | The Big Move | Photo Gallery
