The Canadian Synchrotron Radiation Facility (CSRF) (French: Institut canadien du rayonnement synchrotron – ICRS) was Canada's national synchrotron facility from 1983 to 2005. Eventually consisting of three beamlines at the Synchrotron Radiation Center at the University of Wisconsin–Madison, USA, it served the Canadian synchrotron community until the opening of the Canadian Light Source in Saskatoon, Saskatchewan, finally ceasing operations in 2008.
