In order to avoid overheating and damage, the energy stored in the quenching magnets needs to be quickly and uniformly distributed in the winding pack while maintaining a safe voltage distribution among components. The recently-developed Coupling-Loss-Induced Quench (CLIQ) system is an advantageous alternative to traditional quench protection systems based on quench heaters. CLIQ utilizes inter-filament coupling loss as an effective intra-wire heat deposition mechanism, which by principle is faster than thermal diffusion. Being based on simple and robust electrical components, CLIQ reduces the risk of failure and electrical breakdown. However, its integration in an accelerator magnet circuit requires careful consideration of several interdependent systems, including powering, electrical distribution and cryogenics. We review the principles of the CLIQ method, the validation tests carried out in accelerator magnets so far, its planned use in the high luminosity LHC, and the general outlook for application to future accelerators.
