At Esrange, SSC has a research infrastructure for optical instruments for atmospheric research, called KEOPS. The existing infrastructure consists of a number of individual small buildings of 2 sqm each, where several research institutes and universities have placed their optical instruments. The goal of the project is to facilitate the work at the infrastructure, and to attract several research actors to place their instruments at KEOPS, by replacing the small buildings with a common building for all instruments. This would facilitate the work of the instruments, and also make the infrastructure less weather-sensitive, thereby extending the lifetime of the instruments. A joint building where different research teams can conduct experiments would potentially lead to more research collaborations and make Norrbotten a more attractive research region. Construction of the building is procured during the project, in close dialogue with the target group, i.e. the researchers who currently have instruments at KEOPS.
