CERN to build new 100 km-long particle accelerator - Geeko

CERN, the European organization for nuclear research, has announced plans to build a new particle accelerator with a record length of 100 kilometers. This new physics instrument will succeed the Large Hadron Collider, CERN's current particle accelerator 27 kilometers long and holder of the title of the largest particle accelerator in the world. He is based in Geneva, Switzerland.

“An accelerator propels charged particles [electrically], like protons or electrons, at very high speeds, close to that of light. They are then projected onto a target or against other particles, traveling in opposite directions. These collisions allow physicists to probe the infinitely small, ”explains CERN on its site.

On the boson hunt

By developing a new instrument of this type of record length, the European Council for Nuclear Research (CERN) wishes to continue its research on the Higgs boson, a particle theorized by Peter Higgs and several other scientists in 1964 and identified by CERN in 2012 thanks to the Large Hadron Collider.

With an electron-positron accelerator 100 kilometers long - and without going into details - CERN researchers will be able to try to explain the laws of the Universe and therefore all of the physical phenomena around us from from the Higgs boson. Future superconstruction will also make it possible to envisage new forms of physics, notably supersymmetry or dark matter.

Beginning of construction in 2038

A particularly ambitious project which should not yield results for very many years. The construction of the 100 km long particle accelerator should indeed start only in 2038, in Geneva and last several years. Several countries are expected to participate in the funding of this new physics instrument project, as was the case for the Large Hadron Collider. The new model is expected to require a budget of more than 21 billion euros.

Meanwhile, the High luminosity large hadron collider project, which is an upgrade from the current Large Hadron Collider, is expected to be operational in 2026.
