Salerno Collegiate Group of the INFN-Naples Section
Projects:
- PONa3_0007 (joint UniSA, INFN, ENEA and CRdC): installation of the Power Superconductivity Laboratory at the Salerno Campus
- THOR (INFN, UniSA, GSI / FAIR): cryogenic tests of the SIS100 quadrupoles
THOR is the magnetic test stand installation for performing the site acceptance test (SAT) of the quadrupole modules before installing them into the SIS100 syncrotron. This special program is carried on behalf of GSI / FAIR (Darmstadt), according to signed MoUs GSI / INFN and GSI / University, within the Laboratory for Power Superconductivity set at the University of Salerno campus. Activity was set in 2017 with the adaptation work still in progress. The test phase is actually scheduled 2020-24.
