New Circular Collider Proposal Dwarfs Large Hadron Collider

It is a four-volume document that presents the different options for a large circular collider of the future.

"The FCC conceptual design report is a remarkable accomplishment", commented CERN director-general Fabiola Gianotti.

A conceptual design report was issued on Tuesday, Jan. 14.

"While presenting new, daunting challenges, the FCC would greatly benefit from CERN's expertise, accelerator complex and infrastructures, which have been developed over more than half a century", said Bordry. Since then, no new particles were at the LHC, however, have been sighted - much to the Regret of the particle physicists, who had cited as a Motivation for the construction of the LHC, the search for particles beyond the standard model, such as supersymmetric particles, or candidates for the mysterious Dark matter. The new CDR contributes to the European Strategy.

CERN has been planning their next generation collider for years. The design for the FCC would be some 100 kilometers (62 miles) long and, when operating at full capacity, collide particles at 10 times the energy of the LHC.

Preparatory work on the FCC began in 2014, imagining a machine capable of providing "electron-positron, proton-proton and ion-ion collisions at unprecedented energies and intensities, with the possibility of electron-proton and electron-ion collisions".

The FCC design study was a huge effort, possible only thanks to a large global collaboration. The Future Circular Collider would be almost four times larger than the LHC and aim to fill gaps in our knowledge of the universe.

In terms of scale, the FCC would be nearly four times the length of the LHC at 100km, comprising a superconducting proton accelerator ring at an order of magnitude many times more powerful than its predecessor. "This would enable a rich program to benefit the particle physics community throughout the 21st century". The new FCC proton collider would reportedly need $16bn of funding (around £13bn or AU$22bn) to dig out the 100km tunnel and build the complex research equipment for its experiments.

The new collider would be a decadeslong project that would cost up to $24 billion. The organisation said the discovery of the particle "opened a new path for research" and created a "door into new physics". These precise measurements would provide great sensitivity to possible tiny deviations from the Standard Model expectations, which would be a sign of new physics.

The cost of the initial electron-positron collider (EPC) would cost around 9 billion euros, while the 100-km tunnel to house it would cost an additional 5 billion.

China has also announced plans past year to build a similarly sized accelerator, aiming for a 20-mile diameter ring, and 5x the LHC output.

'A large proton collider would present a leap forward in this exploration and decisively extend the physics programme beyond results provided by the LHC and a possible electron-positron collider'.
