The National Accelerator Centre (CNA) is a joint centre operated by the University of Seville, the Regional Government of Andalusia and the Spanish National Research Council (CSIC). It is a Unique Scientific and Technical Infrastructure (ICTS) dedicated to interdisciplinary research and, therefore, is open to external users.

It features six different systems: a 3 MV Van de Graaff Tandem accelerator, a Cyclotron providing 18 MeV protons and 9 MeV deuterons, a 1 MV Cockcroft-Walton Tandem accelerator used as a mass spectrometer, a PET/CT scanner for humans, a new radiocarbon dating system known as MiCaDaS, and a Co60 Irradiator.

The application of these six infrastructures covers fields as varied as materials science, environmental impact, nuclear and particle physics, nuclear instrumentation, medical imaging, biomedical research and pre-clinical molecular imaging and dating, medical imaging in patients, carbon-14 dating and irradiation of samples of technological and biological interest.
