Insertion Devices Development Projects

The near-term R&D of the Insertion Devices at MAX IV consists of:

  1. Compact APPLE X undulator with a round aperture for the generation of Soft X-ray. A cost-effective solution compared to the existing APPLE II and provides full polarization control with constant effective K-value as a function of phase, i.e. polarization state. The APPLE X is an ideal source for the proposed soft X-ray FEL at MAX IV and gives the possibility to extend the energy range below 2 keV at the FemtoMAX beamline at the SPF. In addition, it offers higher energy range with full polarization tunability at the 3 GeV MAX IV ring compared to the APPLE II undulators.
Apple X
  1. Short period Cryogenic Permanent Magnet Undulator CPMU for future hard X-rays beamlines. Period length of 12 – 14 mm and physical gap in the range of 3 – 3.5 mm to extend the hard X-rays range beyond 65 keV with high brilliance at the 3 GeV MAX IV ring.

Magnetic Measurement Laboratory

The ID group is responsible also of magnetic measurements laboratory at MAX IV. The lab is used for in-house development, construction and characterization of ID’s, which is a key tool to meet the tight requirements of the MAX IV accelerators on the ID’s field quality. The magnetic measurements systems consist of hall probe bench, stretched wire system, and flip coil system.
