CERN Reveals Plans For 100-Kilometer Future Round Collider

It would sit next to the current 27-kilometer (17-mile) circumference Large Hadron Collider near Geneva, which is perhaps best known for helping confirm the subatomic Higgs boson in 2012.

This week an worldwide collaboration of scientists and researchers published its Conceptual Design Report for the Future Circular Collider (FCC). The aim would be to create a collider able to generate 100TeV that would lay the basis for 21st-century high-energy physics and answer questions about the Standard Model that the LHC raised, but was unable to answer.

Once activated, the FCC's lifespan will be between 15 and 20 years.

The research underpinning the machine's creation comprised of more than 1,300 researchers from 150 universities, research institutes and industrial firms. Finally, protons will be made possible collisions in the 100-Kilometer-long Tunnel at center of mass energies of up to 100 teraelectron volts - the latter Design, however, would only be taken after the successful implementation of the electron-Positron accelerator in attack and, thus, in the late 2050s years. CERN Director-General Fabiola Gianotti said that the FCC would benefit significantly from the expertise, accelerator complex, and infrastructures that were developed over the last 50 years.

CERN's famous Large Hadron Collider spanning two countries is only the beginning, with new plans for an even larger system.

The first of these stages would collide electrons and positrons.

Reaching energies of 100 teraelectronvolts and beyond would allow precise studies of how a Higgs particle interacts with another Higgs particle, with thorough exploration of the role of the electroweak-symmetry breaking in the history of our universe.

Scientists have announced plans for the largest experiment ever conducted - a £21 billion plan to find a "theory of everything". The machine-which is estimated to cost around $10.25 billion-would have the capability to detect new, rare processes and measure known particles with now unobtainable precision.

"The FCC's ultimate goal is to provide a 100-km superconducting proton accelerator ring, with energy of up to 100 TeV, meaning an order of magnitude more powerful than the LHC", said CERN Director for Accelerators and Technology Frederick Bordry.

The discovery of the Higgs boson at the LHC opened a new path for research, as the Higgs boson could be a door into new physics. If the collider gets the go-ahead, it could be up and running by 2040. The proton accelerator that would go to 2055 in operation, would cost about an additional 15 billion euros.

The CDR is part of a roadmap to be drawn up by particle physicists as an update to the European Strategy for Particle Physics.
