LHC

The final superconducting magnet built in the U.S. for the high-luminosity upgrade to the LHC has left Berkeley Lab on its way to CERN for the first stage of its journey. The magnets are the result of over twenty years of dedicated R&D with contributions from Fermilab.

CMS scientists recently formed the first prototype “cassette” for the new endcap calorimeters which will be the largest silicon-based detectors ever built when complete. This technology will increase in the number of particles that the HL-LHC will deliver and result in 4 to 5 times more simultaneous particle collisions than occur with the existing LHC.

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate.

Some friendly competition between the CMS and ATLAS experiments led up to the first discovery of entanglement at the Large Hadron Collider.

Physicists in the United States support the development of an off-shore Higgs Factory — a collider perfectly tuned to mass-produce Higgs bosons.

The Magnet Detectives investigates the story of the assembly of the US-built magnets for the high-luminosity upgrade to the Large Hadron Collider. By doubling the number of protons inside the LHC and improving the beam dynamics, the upgrade will increase experimental datasets by a factor of 10.

As upgrades enable the LHC to produce more and more particle collisions, physicists are using machine learning to keep up with the growing task of sorting through everything.

In a race against the clock, CERN engineers and technicians pulled together to find and fix a leak inside the Large Hadron Collider.

Indirectly testing this theory, motivated by the mysterious mass of the Higgs boson, could be within reach for experiments at the Large Hadron Collider.

Berkeley Lab completed winding more than 2000 kilometers of superconducting wire into cables for new magnets that will help upgrade the Large Hadron Collider. These cables will be used to make the strongest focusing magnets installed in any accelerator by condensing particle beams right before they collide in detectors.
