MaTeRiA EU/National Funding PON Ricerca e Competititvità 2007 2013 Scientific responsible: Prof. Mauro Ghedini MaTeRiA is a joint project aimed at developing a new Research Infrastructure inside the University of Calabria campus area Partners: UniCal, The University of Calabria & CNISM, Italian Consortium on Physical Sciences of Matter (1300 reasercher from 39 universities) Funding 15.700.000 8.4 M STAR source - CNISM 6.6 M Laboratories and building - UniCal 0.7 M Master program UniCal Start Date: 01.01.2012 End Date: 31.12.2014
MaTeRiA CENTER Sito STAR The highly specialized laboratories that constitute MaTeRiA will be organized in three progressive levels First level. STAR (Southern Europe Thomson Back-Scattering Source for Applied Research) equipped with the beam-line µtomo. Second level laboratories: 1. Preparation and characterization 2. Characterization of the mechanical and physical properties 3. Modeling and simulation 4. Prototyping 5. Advanced spectroscopy Third level. Network of existent departmental laboratories
