CERN plans to build a new, much larger accelerator

CERN's existing 27km diameter underground particle accelerator is the world's largest scientific . But CERN scientists are already making plans for an even more gigantic cthe accelerator with a diameter of 80 to 100 kilometers, which will be up to seven times more powerful than the current one.

At a meeting to be held at the University of Geneva next week (February 12 to 15), according to the French Agency and the "About 300 physicists and engineers, led by CERN General Manager German Rolf-Dieter Hoyer, will present plans for the successor to the existing accelerator.

Today's "Large Hadron Collider" (LHC), launched under the Flemish-Swiss border of 2008 and expected to operate until 2030, can make proton collisions up to 7 TeV (tetraacetinolite), which will double in 14 TeV from 2015. But his successor will be able to reach 100 TeV, an energy that will allow him to "deepen" deeper into the secrets of matter and the universe.

"The time has come to look even further into the future," says a statement from the European Organization for Nuclear Research (CERN), which last year celebrated the great success ς του μποζονίου του Χιγκς. Αυτή την περίοδο ο επιταχυντής βρίσκεται σε φάση διακοπής λειτουργίας για λόγους συντήρησης και αναβάθμισης, μια διαδικασία που θα διαρκέσει 18 μήνες έως τις αρχές του 2015.

Given that ambitious plans, such as the construction of an accelerator, require a long time from the initial capture to their realization, it was considered appropriate to take advantage of the LHC's temporary respite to help scientists slowly figure out who will succeed the current accelerator.

Thus, next week the five-year period will officially begin σκοπιμότητας για την (πιθανή αλλά όχι βέβαιη) δημιουργία του λεγόμενου «Μελλοντικού Κυκλικού Επιταχυντή» (Future Circular Collider-FCC), που αποκαλείται και “TLEP”, ο οποίος πιθανώς θα βρίσκεται στην ίδια and will integrate the LHC tunnel into its much larger infrastructure, according to its announcement CERN. In fact, the proposal is to create two accelerators in the same 100 km tunnel, first one for electron and positron (TLEP) collisions, and in the next phase a larger proton collisionFCC).

The planned giant FCC, however, has to compete with a more "mature" and cheaper alternative proposal for the creation of a linear - not circular - accelerator, either the 80 km long Compact Linear Collider (CLIC), or the 31 km long Linear Collider (ILC). The big dilemma is whether the next big accelerator will be circular or linear, and then once that is decided, the exact design of the accelerator needs to be finalized.

The two feasibility studies will compare costs and benefits for the circular and linear accelerator. The final choice is expected to become 2018-19 when the new European strategy in the field of particle physics will be formally drawn, of course in consultation with Europeans with other countries, which are also partners CERN.

The winner "will be a worthy successor to the LHC," he said CERN and added that the new accelerator "will allow particle physics to push the frontiers of knowledge even further." Among other things, the aim will be to provide a definitive answer as to whether the widely held (but not experimentally proven) theory of supersymmetry, according to which every subatomic particle in the has a "mirror" (symmetric) particle. Future research will also focus on the mysterious "dark" matter, which is estimated to be far more abundant than conventional matter in the universe, but whose existence has so far been inferred indirectly rather than from direct observations.

The original idea for the current accelerator LHC it existed in the early 80s, approval for its creation was given in the 90s, and its construction, completed in the late 2000s, cost around 4,1 billion euros.

Its successor will of course also take decades to complete - and the question is whether governments will be given such large amounts of funding, especially if the cuts in public budgets continue. The bulk of the costs will be the construction of the new huge underground tunnel, part of which may even be beneath the Lake of Geneva.
