The PhotoEmission Electron Microscope (PEEM) principally consists of electron optics for performing spatially resolved spectroscopy and topography on samples, manipulated within a ultrahigh vacuum (UHV) environment.
The beamline combines high spatial resolution with high flux density to resolve nanostructures on nanometer length scales. Through the PEEM, the Nanoscience beamline is able to resolve nanoparticles with diameters of less than 20nm, using polarized soft x-rays. The PEEM has been designed and built in such a way that future upgrades to improve the spatial resolution can be added as technology develops.
In addition to the PEEM, the instrument also has a high stability electron gun in order to perform Low-Energy Electron Microscopy (LEEM). The LEEM consists of an electron gun which illuminates the sample with a monochromatic beam of electrons of tuneable energy and diameter.
State-of-the-art sample preparation facility is available which includes LEED, Auger and STM.
I06 is a polarised spectroscopy and microscopy beamline equipped with a PEEM, 6 T low temperature (1.5 K) superconducting magnet, 2 T vector magnet as well as soft X-ray diffraction vacuum goniometer.
