The synchrotron radiation and free electron laser project MAX IV at MAX-lab

The proposed MAX IV facility at MAX-lab, Lund University is presented. The project consists of two storage rings at 1.5 and 3 GeV respectively, a 3 GeV linac injector, a facility for short pulses and a Free Electron Laser. The storage rings will cover a broad spectral range and are designed to reach the diffraction limit in a large wavelength range. A new innovative magnet concept and lattice form the back bone of the ring design. Short photon pulses will be generated with compressed pulses from the linac system and coherent pulses by a Free Electron Laser operating in the HGHG mode. The project has received the highest marks in the scientific evaluations both concerning machine design and scientific program
