ALBA is a third generation synchrotron light source facility, designed to provide a high brilliance photon beam. It is co-financed by the Spanish Government and the regional Government of Catalonia, and managed by the Consortium for the Construction, Equipment and Exploitation of the Synchrotron Light Laboratory (CELLS). The accelerator complex consists of a 100 MeV Linear Accelerator (LINAC), a Booster that ramps the electron beam energy up to 3 GeV and a Storage Ring. The maximum operational current is 250 mA and it will be operated soon in top up mode. Currently, ALBA has 10 beamlines in operation.

ASTRID2 is the new third-generation low-emittance light source at Aarhus University, Denmark. Commissioned in 2013, the new facility provides state-of-the-art high-brilliance light from the low-emittance electron beam, operating in top-up mode to give an infinite beam lifetime.

The third generation storage ring BESSY II is in operation since 1999 and provides ultrabright photon beams from the long wavelength Terahertz region to hard X-rays with complete control of the energy range and the polarization of the radiation. The facility is operated by the Helmholtz-Zentrum Berlin.

DAΦNE-Light is the Synchrotron Radiation Facility at the INFN Frascati National Laboratory. The radiation source DAΦNE is an electron-positron collider that works at 0.51 GeV with beam currents higher than 1 A in operation since 1998.

Diamond is a 3rd Generation 3GeV synchrotron light source which has a 1MeV linear accelerator (Linac), and full energy (1MeV-3 GeV) Booster. Top-Up mode became available in 2008. Diamond has been operating since January 2007, when the first 7 beamlines became operational. By the end of 2012 the number of operational beamlines increased to 22, with 33 operational by 2022.

The third-generation electron storage ring Elettra, operated by the Elettra Laboratory of Sincrotrone Trieste S.C.p.A. since 1993, feeds 27 beamlines. Researchers from more than 50 different countries, selected by an international committee on the basis of the quality of their scientific proposals, access the facility each year.

The European Synchrotron Radiation Facility (ESRF), located in Grenoble - France, is a joint facility supported and shared by 22 countries. The ESRF operates the most powerful synchrotron radiation source in Europe. Each year several thousand researchers travel to Grenoble where they work in a first-class scientific environment to conduct exciting experiments at the cutting edge of modern science.

The MAX IV facility comprises two low emittance storage rings (1.5 GeV and 3 GeV) and a 3 GeV linac injector which also serves as a source for femto-second X-ray pulses. The novel multi-bend achromat design of the 3 GeV storage ring leads to an emittance below 0.3 nm rad which reveals the high brightness of this storage ring-based light source. At present, there are 16 beamlines in operation: ten at the 3 GeV ring, five at the 1.5 GeV ring and one at the short pulse facility (SPF) at the MAX IV linac. Two more beamlines are on the construction phase. Different calls to use the MAX IV facility are being open, since December 2016, as new beamlines are becoming operational.

PETRA III, which took up operation in 2009, is the most brilliant storage-ring-based X-radiation source in the world for high energy photons. It offers outstanding experimental opportunities for scientists who want to investigate very small samples or require tightly collimated and very short-wavelength X-rays for their experiments.

SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) is a third-generation synchrotron light source under construction in Allan (Jordan). It will be the Middle East's first major international research centre.

The Swiss Light Source (SLS) at the Paul Scherrer Institut is a third-generation synchrotron light source. In the design of SLS a high priority was given to the items quality (high brightness), flexibility (wide wavelength spectrum) and stability (very stable temperature conditions) for the primary electron beam and the secondary photon beams.

SOLARIS is a Polish national research centre providing scientists with synchrotron radiation. The National Synchrotron Radiation Centre functions under the auspices of the Jagiellonian University. The Centre was built between 2011 and 2014. The excellent parameters of the SOLARIS synchrotron put it in the forefront of this type of devices in the world.

SOLEIL is the French national 2,75 GeV third generation synchrotron installation. CNRS and the CEA created the public company SOLEIL Synchrotron, called to lead the construction and then the operation of SOLEIL. Alongside them, the Region Ile de France and the Conseil General de l’Essonne have insured nearly 80% of capital costs. The Region Centre is also a SOLEIL partner.
