Awesome! I had a good nose about the LHC when I was there a few years ago. I'm guessing that site isn't quite so enthusiastic about visitors?
The dump load for one of my wind turbines is a pair of 22Ω resistors recovered from one of CERN's "free for all" scrap piles :-)
Brookhaven does classified research and access to the site is pretty restricted. The last time I visited there were guards with assault rifles at the gates. In comparison, Fermilab used to (and may still) let you walk onto the campus and wander about.
It's a Department of Energy facility. The primary purpose of the DOE is to further the development of nuclear weapons.
