The MAX IV Laboratory, through its MAX-lab facility, has been offering synchrotron light to a broad international research community for more than 30 years. In December 2015 the MAX-lab facility was closed and the laboratory has moved to a new site where the MAX IV project is under completion. The MAX IV facility will comprise two low emittance storage rings (1.5 GeV and 3 GeV) and a 3 GeV linac injector.

The novel multi-bend achromat design of the 3 GeV storage ring leads to an emittance below 0.3 nm rad which means that it will become the world's brightest storage ring-based light source.

The 3 GeV linac accelerator will be used for both injection and top up in the storage rings, and as a driver for the Short Pulse Facility (SPF). When used as a short pulse driver it will be able to deliver sub-100-fs pulses with an emittance below 2 mm mrad at 100 Hz. 

The construction and commissioning of these new experimental facilities are well under way and it is foreseen that the first beamlines will become operational during the second half of 2016 with user operation starting in the beginning of 2017. At present, 14 beamlines are funded for the MAX IV facility: Eight 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.
