As mentioned on other occasions, the HL-LHC IT String is a key milestone for the High Luminosity LHC (HL-LHC). It will enable the project to test the collective behaviour of some of the major components which have been designed for the new era of the accelerator. State-of-the-art technologies and operating schemes (in terms of cooling, powering, and protection of Inner Triplet (IT) magnets and circuits) will prove their importance in this test stand, Accelerating News.
