CERN removes first giant beam absorbers from LHC, making room for High-Luminosity Large Hadron Collider upgrade
CERN recently completed a complex transport operation, moving the first two giant components from the Large Hadron Collider (LHC) tunnel to the surface, making room for the operation and upgrade of the future High-Luminosity Large Hadron Collider (HiLumi LHC). The equipment removed this time consists of two beam absorbers, also known as TAN absorbers. Each absorber is about 5 meters long and weighs about 30 tons, made of iron, copper, and marble, primarily used to protect accelerator magnets from damage caused by neutral particles generated along the beam direction during collisions. A relevant official stated that this type of equipment is among the heaviest and largest devices that need to be removed from the LHC during this shutdown period...

CERN Accelerator Complex Enters Full LS3 Shutdown for Upgrades, Paving the Way for the High-Luminosity LHC Era
On the morning of August 31 local time, the injector complex and the Antimatter Factory at the European Organization for Nuclear Research (CERN) ceased operation after completing their final beam deliveries, officially entering the third Long Shutdown (LS3) phase. Earlier, the Large Hadron Collider (LHC) had been closed in June, marking the flagship accelerator as the first to kick off LS3 upgrade work at the center. Bettina Mikulec (left), head of the Operations Group at CERN, handed a symbolic baton—a miniature superconducting magnet from the LHC—to Jean-Philippe Tock (right), head of the LS3 Coordination Group, with CERN Director-General Mark Thomson (second from left) and Oliver Brüning (third from left), head of Accelerators and Technology, in attendance.

U.S. Brookhaven National Laboratory Achieves Milestones in High-Luminosity Large Hadron Collider Upgrade
On July 29, the Large Hadron Collider (LHC) at CERN concluded its recent run and entered a four-year shutdown for maintenance. During this shutdown, some LHC components will be dismantled and rebuilt for the High-Luminosity LHC (HiLumi LHC) upgrade project. The U.S. Department of Energy's Brookhaven National Laboratory has recently achieved important production milestones in both accelerator and detector-related work. The LHC helps scientists study the fundamental structure of matter by accelerating and colliding two beams of protons traveling in opposite directions in a nearly 17-mile circular ring. The core goal of the HiLumi LHC upgrade is to significantly increase the number of particle collisions per unit time, i.e., enhance "luminosity," thereby increasing the chance of recording rare interactions.
