Development of MgB2 superconducting magnets supported by MIUR (Italian Ministry of Research)

Research project in partnership with  the National Institute for the Physics of Matter (CNR-INFM) - Units of Salerno and Naples.

The research is aimed at the design and manufacturing of cryocooler cooled MgB2 magnets.

Duration : 48 months (started on 01.06.2003).
