polarizing devices

High performance Fe/Si supermirrors are employed to the polarizing supermirror devices. The characteristics of the coatings are:

  • Fe/Si polarizing supermirror with high reflectivity up to
    m = 5.5, polarization approaching 100% (Fig. 1)

  • highly reproducible large scale fabrication

  • approved long-term stability and radiation resistance

  • low internal stress

These enable for various kinds of devices:

  • V- & Z-cavities - single-/multi-channel

  • reflection polarizers

  • benders

    • conventional & solid state

    • reflection & transmission

    • S-type - conventional & solid state

  • radial benders for wide angle polarization analysis

In addition SwissNeutronics produces dedicated focusing arrays for Heusler monochromators.
