Excellent research requires access to high-quality research infrastructures. European and national funders are supporting European and national infrastructures while local research infrastructures, which can also be national and international, are the responsibility of the universities.
Research infrastructures are tools for research that are too extensive and too long-term for individual research groups to be able to operate them. Research infrastructures are different for different areas. It can for example be large facilities for materials science or physics studies or distributed databases for research in humanities, social sciences and medicine.
