Exactly so: look at the Cern website. The Cern system has two contra-rotating rings of protons which collide sat crossing points. The second generation version, known as LHC (Large Hadron Collider) fires up this year.

The Large Hadron Collider (LHC) is a particle accelerator and hadron collider located at CERN, near Geneva, Switzerland ( [show location on an interactive map] 46°14′N, 6°03′E). Currently under construction, the LHC is scheduled to begin operation in May 2008.[1][2] The LHC is expected to become the world's largest and highest-energy particle accelerator.[3] http://en.wikipedia.org/wiki/Large_Hadron_Collider ...[EXCERPT from website for you]...

Currently under construction, the LHC is scheduled to begin operation in May 2008.[1][2] The LHC is expected to become the world's largest and highest-energy particle accelerator.[3] The LHC is being funded and built in collaboration with over two thousand physicists from thirty-four countries as well as hundreds of universities and laboratories. When activated, it is theorized that the collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and 'missing links' in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass.[4][3] The verification of the existence of the Higgs boson would be a significant step in the search for a Grand Unified Theory, which seeks to unify three of the four fundamental forces: electromagnetism, the strong force, and the weak force. The Higgs boson may also help to explain why the remaining force, gravitation, is so weak compared to the other three forces. In addition to the Higgs boson, other theorized novel particles that might be produced, and for which searches[5] are planned, include strangelets, micro black holes, magnetic monopoles and supersymmetric particles[6]. .
