What is CLIQ
Recently at CERN, a new, moreefficientandfastermethodcalled CLIQ (CouplingLossInducedQuench) has beendeveloped, implemented in a deviceandsuccessfullyproved. Theprincipal of operation is based on thecapacitor bank dischargeintothesuperconductingmagnetcoil. Theformed LC-ring doesseveralperiodicallydampedoscillations, characterizedby a veryhighdI/dt (seeFigure 2). Theresult in thecoil is highcouplinglosses (heat) generated inside thesuperconductor – exactlywhere is needed, increasingthetemperatureandinitiatingthedesiredtransition.
Thesuccessfulperformance of thefirstprototype of a CLIQ unitbrought a newmandatetotheElectricalEngineeringsection in the MPE group at CERN, todevelopandproduce a morerobustandpowerfulunit. Severalunits of thenewdeviceweremanufacturedandarecurrentlybeingused in thetestsfacilities at CERN fortheprotection of a newgeneration of highcurrentdensitysuperconductingmagnets.

2.3 Itemsand Services providedby CERN
CERN shallprovidethebuild-to-printdesignto be usedforthemanufacturing. A completepackage of assemblydrawings,
electronicschematics, Gerberfiles, etc. will be providedby CERN.
Thecapacitorcharger (seesection 3.5.2.10) foreachunitshall be eithersuppliedby CERN oritsdesign sent tothecontractor.
Ineithercase it should not be included in theoffer (an amendmentwill be madeifneeded).
Thecontractorwill be allowedtocometo CERN toseethecurrent CLIQ prototypesanddiscusswith CERN engineers.
