A special Call for Proposals is now open for any work that will actively contribute to finding COVID-related treatments or vaccines, or improve conditions for frontline workers, including developing sensors and diagnostic tools or special surfaces with antiviral properties.


Research time allocated through the General User mechanism is via competitive peer review emphasizing the excellence of science where there is intent to publish scientific results. A Call for Proposals is issued twice per year for experimental beam time. View participating beamlines
