For significant and continuous contributions to large scale applications of superconductivity; in particular:
for his many contributions in both design and construction of magnets for particle accelerators, including:
the design and construction of the pioneering project Intersecting Storage Rings (ISR) quadrupoles
the realization of the Large Hadron Collider (LHC) magnets at CERN from the design of the first models and prototypes through the difficult and critical phase of industrialization
for the leadership of the magnet group responsible for developing magnets and superconductors at CERN
