Upgrade to Large Hadron Collider that could ‘unlock new dimensions’

The world’s largest particle smasher is kicking off a major upgrade to churn out 10 times more data and help unlock the secrets of physics.

The European Organization for Nuclear Research, or CERN, started work Friday on a project to boost the number of infinitesimal collisions, known as ‘luminosity,’ in its Large Hadron Collider by installing high-tech magnets.

CERN says the upgrade is expected to produce greater data starting in 2026.

CERN, started work Friday on a project to boost the number of infinitesimal collisions, known as ‘luminosity,’ in its Large Hadron Collider by installing high-tech magnets. This means that physicists will be able to investigate rare phenomena and make more accurate measurements.

They said the upgrade will allow the Higgs boson ‘god particle’ to be defined more accurately, and to measure with increased precision how it is produced, how it decays and how it interacts with other particles.

In 2012, the LHC was used to prove the existence of the Higgs Boson—also dubbed the God particle—which has allowed scientists to make great progress in understanding how particles acquire mass.

In addition, scenarios beyond the Standard Model will be investigated, including supersymmetry (SUSY), theories about extra dimensions and quark substructure (compositeness) will be examined.

CERN says the collider ringing the French-Swiss border near Geneva has worked well since operations began in 2010.

CERN, perhaps most famous for confirming the subatomic Higgs boson six years ago, says the budget for the High-Luminosity LHC is about $950 million.

The work involves heavy civil engineering at the LHC’s two main sites in Switzerland and France which are run by Europe’s physics lab CERN, that will allow it to operate in a high-luminosity mode from 2026.

The project will involve the replacement of high-tech components along 1.2 kilometres of the machine, such as magnets, collimators and radiofrequency cavities.

It will also see the construction of new buildings, shafts, caverns and underground galleries, as well as tunnels and halls to house the new cryogenic equipment, as well as power supplies and cooling and ventilation kit.

The HL-LHC requires about 130 new magnets, in particular 24 new superconducting focusing quadrupoles to focus the beam and four superconducting dipoles.

Sixteen brand-new ‘crab cavities’ will also be installed to maximise the overlap of the proton bunches at the collision points.

Their function is to tilt the bunches so that they appear to move sideways – just like a crab.

‘By 2026, this major upgrade will have considerably improved the performance of the LHC, by increasing the number of collisions in the large experiments and thus boosting the probability of the discovery of new physics phenomena,’ CERN said.

The aim is increase tenfold the amount of data which can be picked up by the LHC, which is housed in a 27-kilometre (17-mile) ring-shaped tunnel buried more than 100 metres underground that runs beneath the border of Switzerland and France.

The powerful accelerator, which began operating in 2010, smashes high-energy protons into each other at velocities near the speed of light.

These collisions generate new particles, giving physicists an unprecedented look at the laws of nature in the hope of better understanding particles and matter.
