Giovanni Volpini (2014)

In memory of Giovanni Volpini

July 24, 2017 (PO59). Giovanni Volpini passed away prematurely on the 12th of October 2016, after a three months battle with a subtle and rapidly evolving cancer. He was Senior Researcher of INFN (Istituto Nazionale di Fisica Nucleare), leading the superconducting magnet group of INFN - LASA laboratory in Milan (Italy).

Giovanni obtained his “Laurea” in Physics in 1989 at the University of Milan, with a thesis on particle physics in the UA2 experiment. He then turned to applied superconductivity, obtaining the PhD from the University of Milano in 1993 with a work on the “Transition of multifilamentary composite superconductors” studying the meaning of the n-index and other subtle effects. He then investigated properties of the first LHC superconducting cables, designing and commissioning a sample holder for testing LHC cable up to 30 kA in the LASA lab.

In 1998, he moved to detector magnets, working on the superconducting toroid of the ATLAS experiments. He designed various measuring and testing systems for critical current and joint resistance of the aluminum super-stabilized conductor (rated for 60 kA at 5 T) and followed the industrial production of the conductor, in collaboration with CEA-Saclay.

In 2001, he became responsible for the LASA superconducting magnet group, taking over the responsibility for the construction of the 25 m long superconducting coils for the ATLAS Barrel Toroid. He worked in close collaboration with CEA-Saclay and ATLAS magnet team. He also took care of the thermal shield of the barrel toroid magnet as well as of some critical components for the magnet protection, like the dump system. The success of the ATLAS magnets is due also to his much-appreciated competence and hard work.

At the end of LHC construction in 2008, with the colleagues of INFN-Genoa and in collaboration with the GSI team, he contributed to the design, construction, and test of the first prototype of the SIS-300 pulsed dipole for the FAIR project, which was successfully tested in 2013.

From 2013-2016 he was a member of the EuCARD2 collaboration, for which he started to design and build a variable temperature test facility for the magnet prototype.

In 2014, he joined CERN as Associate to the High Luminosity LHC Project, on leave from INFN, while maintaining the position of group leader at LASA laboratory.  He designed and successfully tested the first of the super-ferric magnets, a new design that will be used in HiLumi LHC for all high-order corrector magnets. This success gained him the confidence of CERN and resulted in assigning to INFN-LASA the construction of all types of super-ferric magnets for the HiLumi LHC project. He could only draw the first plan to accomplish that project; sudden illness took him away for his loved ones, his friends, and colleagues.
