Photon Science Roadmap for Research Infrastructures 2025–2028 by the Swiss Photon Community

This community roadmap summarizes a survey of the Swiss large-scale infrastructure requirements in the broad field of photon science for the years 2025–2028, drawing from the current situation both in Switzerland and abroad. The Swiss Society for Photon Science (SSPh) collected the scientific visions and compiled the needs of the community of photon science, which encompasses all research areas that work to generate, manipulate and detect photons or use them to investigate or control complex assemblies of matter. The roadmap represents the view of the Swiss scientific community in the field of photon science and is a formal element of the process to elaborate the Swiss Roadmap for Research Infrastructures 2023. This bottom-up contribution to the identification and selection of important national and international research infrastructures has been coordinated by the Swiss Academy of Sciences (SCNAT) on a mandate by the State Secretariat for Education, Research and Innovation (SERI).
