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). CLIQ operates through the discharge of capacitors charged up to 600 or 1000 V, depending on the magnet type, and injecting approximately 3 kA AC current into the magnet coils…
