Distributed large technical infrastructure for applied superconductivity dedicated to coordinated developments and tests of superconducting magnets for accelerators and accelerating superconducting cavities: the infrastructure based on large cryogenic facilities is located in four different sections and laboratories (Genova, Laboratori di Legnaro, Milano-LASA and Napoli). All local facilities are equipped with cryogenic plants for liquid helium (bi-phasic, superfluid and supercritical) with cooling power at 4.2K ranging from 100 W to 1100 W. The facilities dedicated to sc magnets can count on large power converters up to 20 kA at 25 V and all ancillary equipment for testing long magnets (up to 8 m) in vertical and horizontal cryostats.
