Completion of series production for the CLIQ machine protection system
The full series production of the Coupling-Loss Induced Quench (CLIQ) system has now been completed and delivered to CERN. CLIQ is a novel protection technology developed at CERN for the superconducting magnets of the High-Luminosity LHC (HL‑LHC).

Third magnet from the USA delivered!
After a long journey from Fermilab in Batavia, Illinois, the third cryo-assembly (named LQXFA04) from the United States Accelerator Upgrade Program (US-AUP) has been successfully delivered to CERN. Having arrived on 6th of August, it will now undergo incoming inspection, followed by a horizontal cold test and finally the second phase of cryostat assembly.

New RF Springs for HL-LHC double-beam collimators
New RF Springs for HL-LHC double-beam collimators By Lucas Hermida Pena (CERN) Collimators are Beam Interaction Devices (BIDs) designed to remove stray particles from the beam bunches which could damage sensitive equipment. Recently, two fully functional prototype double-beam collimators were fitted with new radiofrequency springs and then installed onto the assembly mock-up. In the current
