Insertion Devices

The insertion Devices (ID) group is responsible of design, development and operation of Insertion Devices for the different beamlines at MAX IV Laboratory. Each beamline is fed by an insertion device, undulator or wiggler, which consists of an array of permanent magnets that provide an alternating static magnetic field that forces the electron beam to oscillate and thus radiating photon beam. The different ID’s cover photon energy range from VUV to hard X-rays at the three accelerators at MAX IV, the low emittance 3 GeV ring, the 1.5 GeV ring and the 3 GeV linear accelerator as a source for short pulses.

1. Out-of-vacuum undulators for VUV and Soft X-rays production. It consists of six APPLE II undulators built in-house, one APPLE II and one planar undulators transferred and refurbished from the MAX II ring.
2. In-vacuum undulators (IVU) and wiggler (IVW) for hard X-rays production. Six IVU’s and one IVW at the 3 GeV ring and two IVU’s at the Short Pulse Facility (SPF).

*) Built by industry, In-Vacuum Undulators
**) Built in-house, APPLE II
***) Built by a collaboration with SOLEIL synchrotron
****) Transfer from MAX II ring, refurbished and characterized at MAX IV ID magnet lab
