The U.S. Department of Energy has given the green light for the U.S.-funded portion of the upgrades to the CMS experiment at CERN. The massive overhaul will prepare the experiment for the high-luminosity era of particle collisions at the Large Hadron Collider.
During a routine test, two HL-LHC magnets unexpectedly flatlined. Was it just a coincidence, or did they have a common foe?
An international collaboration is upgrading the CMS detector at CERN to handle the increased number of collisions that the High-Luminosity Large Hadron Collider will produce.
A CERN photographer and videographer writes about his experiences documenting the ongoing upgrade that will turn the Large Hadron Collider into the High-Luminosity LHC.
From CERN, March 24, 2021: A memorandum of understanding (MoU) between CERN and Fermilab, signed on 23 March, details Fermilab’s contributions to the High-Luminosity LHC project.
Higgs-boson pairs could help scientists understand the stability of our universe. The trick is finding them.
The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.
Later this decade, the Large Hadron Collider will be upgraded to the High-Luminosity LHC. What does “luminosity” mean in particle physics, and why measure it instead of collisions?
From CERN, Jan. 26, 2021: This week marks the 50th anniversary of the first proton collisions in CERN’s Intersecting Storage Rings, the first hadron collider ever built. To celebrate, see hadron colliders of the last half-century — including the Tevatron and the Large Hadron Collider — through a historical lens, with an eye toward the quest for high luminosity and new energy frontiers.
From CERN Courier, Jan. 13, 2021: The US LHC Accelerator Upgrade Project, led by Fermilab scientist Giorgio Apollinari, is now entering the production phase in the construction of magnets for the upcoming High-Luminosity LHC, an upgrade of the current Large Hadron Collider. U.S. labs are building magnets that will focus beams near the ATLAS and CMS particle detectors.
