3 N.C.S.R. Demokritos The National Center for Scientific Research Demokritos is situated on the foot of Mount Hymittus at the outskirts of Aghia Paraskevi, a suburb of Athens, and is about 12km to the north from downtown Athens and close to the airport.

4 N.C.S.R. Demokritos : Structure National Center for Scientific Research Demokritos Consists of 5 Institutes (formerly 8) : Informatics and Telecommunications Biosciences and Applications Nuclear and Radiological Sciences, Energy, Technology and Safety (Institute of Nuclear Technology & Radiation Protection + Radioisotopes and Radiodiagnostic Products) Advanced Materials, Physicochemical Processes, Nanotechnology & Microsystems (Institutes of Materials Science + Microelectronics + Physical Chemistry) Nuclear and Particle Physics (Institute of Nuclear Physics + KM3)

5 N.C.S.R. Demokritos : Data sq meters Campus sq meters Building Area Approx. 200 researchers and 500 technicians and administration NCSR-D hosts research infrastructures unique in the country: 5 MW Nuclear Research Reactor (I.N.S.) 5.5 MV TANDEM Accelerator (I.N.P.P.) 250 kv High-current single-stage Accelerator (I.N.P.P.) 17 MeV Cyclotron (to be installed)

6 The 5.5 MV VdG Tandem I.N.P.P. Basic Research Program (35%): Nuclear Astrophysics Nuclear Reactions Applied Research Program (65%): Materials Cultural Heritage Environment Detector R&D for CERN From 1/2012 an Independent International Program Advisory Committee takes over Chair: Prof. Muhsin Harakeh (KVI, Netherlands) First beam delivered in March Major upgrades during (Αριστεία, 150 k ) and (funds by FP7/REGPOT LIBRA project, 700 k ) Open access to more then 40 external users from almost all Greek Universities and Europe (10 MoU signed) Supports various projects funded by: FP7, ESA & EFDA/Fusion Funding attracted during the last 5 years 2,5 M Education (2005-today): 26 Diplomas, 6 Master s, 11 PhD Unique installation in Greece, one of the few now available in Europe Total investment: 10 M (scientific infrastructure) + 12 M (building with shielding)
