physicists at the biggest particle accelerator in the world, a future-planning project of gigantic dimensions and cost. If your plans are to be implemented, the European organization for nuclear research (Cern) in the French-Swiss border near Geneva, is a 100 km long ring-shaped Tunnel partly under lake Geneva. In the accelerator, Future Circular Collider (FCC), for a total of 24 billion euros are estimated, would be brought from the end of the thirty years electron and a positron on collision course. For comparison: The existing particle accelerator, the LHC, a 27 kilometre long Tunnel.

“The project would be in the Geneva basin, a well realize,” said study leader Michael Benedikt, the German press Agency, to the publication of the concept study in Geneva. The existing equipment could continue to be used, such as a pre-accelerator. The Cern physicists are looking for, among other things, findings on the first nano-seconds after the big Bang and the origin of the universe. In addition, you want to demonstrate a previously unknown particle.

The existing LHC is expected accelerator will run for 20 years, said Benedict. He was off work in December for two years of maintenance. In Parallel, work is already underway on an Expansion with stronger magnets, the so-called HiLumi LHC project. It’s supposed to be 2025 finished. The physicists want to increase the number of proton collisions per second from one to five billion.

First of all, works in the new Tunnel electrons and positrons to collide. The FCC would be up to 100,000 times more powerful than existing systems at Cern, Benedict. After 15 years of operation, the machine could be replaced by a proton accelerator that would be in both collision energy and the number of collisions approximately ten times as powerful as the HiLumi project. The proton accelerator would use the same 100-Kilometer-long Tunnel.

The Cern physicists have presented their concept in the framework of the currently discussed new European strategy for particle physics. By 2020, scientists from all over Europe want to give recommendations on how particle physics can be brought forward.

Whether or not the new particle accelerator is built, one must decide the 22 member States of Cern. The project would cost in the first Phase, nine billion Euro. The proton accelerator that would go to 2055 in operation, would cost about an additional 15 billion euros.
