An overview of the insertion devices (ID) activities at MAX IV Laboratory will be presented. This paper describes the current status of the MAX IV insertion devices and the first commissioning results of some of the first 12 IDs installed at the three accelerators in MAX IV laboratory. The IDs are two Elliptically Polarizing Undulators (EPU), two In-Vacuum Undulators (IVU) and one In-vacuum wiggler installed at 3 GeV ring, four EPUs and one planar undulator in the 1.5 GeV ring and 2 IVUs at the Short pulse facility installed at the 3 GeV Linear accelerator for spontaneous emission.
The impact of the first commissioned IDs on the electron beam in terms of orbit distortion and machine optics and the correction schemes to reduce these effects are described. The comparison between collected spectra from few beamlines and estimated photon flux based on magnetic field measurement maps is presented.
