The magnet lattice of the MAX IV storage rings

In English A successor of the present MAX facility is currently being studied. This proposed MAX IV facility will then have two new storage rings operated at 1.5 and 3 GeV respectively. The magnet lattices of the two storage rings are almost identical and the rings are placed coaxially, one on top of the other. A third ring, the MAX III ring, now under construction, should be transferred to the new facility. These three rings will then offer dipole IR radiation and undulator radiation from 5 eV up to 20 keV. The total number of straight sections is 32, of which 28 could be used for insertion devices. A 3 GeV linear accelerator will be used as injector for the three rings. The linac could also be used as a free electron laser source. The magnet lattice of the two new rings is described below. The electron beam emittance of the 3 GeV storage ring is 0.86 nm rad and 0.3 nm rad for the 1.5 GeV ring. The circumference of the rings is 286 m
