To enhance the scientific cooperation in the Baltic sea region, the international online Symposium „Photon and Neutron Science in the Baltic Sea Region“ will be held online on October 26-29, 2020. Symposium will consist of two parts: an international online conference (26. October) and hackathon (27-29. October). The researchers, stakeholders from large- and small-scale research infrastructures, their users and also the industry are invited to share their visions how research could be carried out in traditional and ‘novel’ ways of using photons and neutrons as methods. The ideas shared and generated during the online conference will be further elaborated on and developed during the hackathon.
