synchrotron radiation Synchrotron radiation (also known as magnetobremsstrahlung radiation) is the electromagnetic radiation emitted when relativistic charged particles are subject to an acceleration perpendicular to their velocity (). It is produced artificially in ...

facility in Lund, Sweden. Its design and planning has been carried out within the Swedish national laboratory, MAX-lab, which up until 2015 operated three accelerators for

research: MAX I (550 MeV, opened 1986), MAX II (1,5 GeV, opened 1997) and MAX III (700 MeV, opened 2008). MAX-lab supported about 1000 users from over 30 countries annually. The facility operated 14

beamline In accelerator physics, a beamline refers to the trajectory of the beam of particles, including the overall construction of the path segment (guide tubes, diagnostic devices) along a specific path of an accelerator facility. This part is either ...

s. The smaller storage ring (circumference 96 meters) is operated at 1.5 GeV energy and has been optimized for UV. There are also plans for a future expansion of the facility that would add a free-electron laser (FEL) to the facility, but is yet to be funded. There are currently 16 beamlines at the facility with 10 of them located around the 3 GeV ring, 5 around the 1.5 GeV ring and one at the of the linear accelerator.
