Research and advanced training at the Gran Sasso Underground Laboratory: a review.

LNGS (Laboratorio Nazionale del Gran Sasso) is a world-class international facility for deep underground science, which has been in operation since 1987. The LNGS has pioneering the development of astroparticle physics and research for rare events in a number of aspects. LNGS is operated as a facility hosting multiple experiments. At present, it hosts experiments searching for dark matter, solar neutrinos, neutrinoless double beta decay, nuclear astrophysics, biology, and geophysics. The LNGS is equipped with ancillary facilities in underground and on surface to support experiments and R&D activities. The LNGS is putting forward an innovative facility for the development of new photosensors to be used in the search of rare events, and an original effort for producing ultra radio-pure copper. Some activities are carried out in collaboration with other underground facilities. The LNGS is a research infrastructure with a broad opportunity for young researchers thanks to the associated GSSI graduate school, located in the close city of L’Aquila, and to fellowships offered by INFN. In addition, the LNGS has an advanced training program for young people with financial support from local authorities. This talk presents an overview of the LNGS main present characteristics and future prospects.
