CERN begins removing magnets from Large Hadron Collider for major upgrade

The short version

• CERN has started dismantling collider sections near the ATLAS and CMS experiments to replace key magnets.[ScienceDaily]
• Crews cut the first interconnection as part of the ongoing High-Luminosity LHC project.[ScienceDaily]
• The replacement superconducting magnets are designed to create fields roughly 40% stronger to increase collision rates.[ScienceDaily]
• The first replacement quadrupole magnet is scheduled to be installed in the tunnel in early 2029.[ScienceDaily]

Key facts

• CERN teams began dismantling sections of the collider on both sides of ATLAS and CMS on September 7.[ScienceDaily]
• The magnet replacement effort is part of the High-Luminosity upgrade during the facility's third long shutdown.[ScienceDaily]
• Technicians recently severed the initial magnet interconnection to formally start the hardware replacement work.[ScienceDaily]
• The upgraded superconducting magnets will produce fields about 40% stronger to compress particle beams more tightly.[ScienceDaily]
• The first new triplet quadrupole is expected to enter the accelerator tunnel at the beginning of 2029.[ScienceDaily]
