We all have read so many popular and media articles on the physics of the LHC. However, we don't see many articles on how it actually works, and what's under the covers. That's why this article is rather interesting. It describes the nuts and bolts of the operation at the LHC. In particular, it gives a rather concise description of the acceleration mechanism, beam dynamics, and diagnostics at the LHC. This, of course, is not a "sexy" piece of information and therefore, does not get a lot of media coverage and the public's attention. Still, it is a crucial piece to the LHC, without which, they can't hunt for the sexy science.
