The Institute of Nuclear and Particle Physics (INPP) of the National Centre for Scientific Research “Demokritos” conducts high-level experimental and theoretical research in High-Energy Physics, Nuclear Physics and Astro-Particle Physics, promoting scientific excellence, innovation and advanced technological applications aligned with national and European research priorities.

INPP’s research activities focus on the study of fundamental particles, nuclear matter and cosmic phenomena, contributing to the advancement of knowledge in frontier areas of modern physics. The Institute actively participates in major international collaborations, including the CMS and ATLAS experiments at the Large Hadron Collider (LHC) at CERN, as well as the KM3NeT, HYPER-K and ANNIE experiments, strengthening the international presence of the Greek research community in fundamental physics research.

The Institute’s Detector Instrumentation Laboratory (DIL) and Data Acquisition, Monitoring and Analysis Laboratory (DAMA) develop advanced detector technologies, electronics and data systems with applications in both basic research and innovation-driven technologies. INPP also hosts the unique 5.5 MV Tandem Accelerator in Greece, an open-access national research infrastructure supporting interdisciplinary applications in cultural heritage, environment, energy, health and advanced materials research.

Through internationally recognized scientific activities, advanced research infrastructures and strong participation in global collaborations, INPP contributes significantly to the advancement of fundamental physics, technological innovation and scientific education in Greece and internationally.
