FOCUS SPLEED
Electron Spin Polarization Detector
The electron spin polarization detector FOCUS SPLEED is based on the principle of Spin Polarized LEED
. It employs low energy electron diffraction by an W (100) single crystal at about 104 eV scattering energy. The detector is based on a patented design developed at the
KFA Jülich by Prof. Dr. J. Kirschner:
- Simultaneous measurement of both transversal components of the spin polarization vector
- Very compact design, fully UHV compatible
- Full package comprising spin detector, electronics and software for integration into the
energy analyser CSA 300 or into the ARUPS analyser SHA 50
- Simultaneous measurement of the standard ESCA, Auger or UPS spectra and their spin resolved components using the CSA 300
- Stand alone version for integration into other energy analysers or scanning electron microscopes (SEMPA)
- OMICRON Product Line CSA 300 with SPLEED
Applications
The requirement for UHV makes the SPLEED the ideal choice for surface science experiments:
- Magnetism in the bulk and at the surface of metals is an area of research where spin resolved UPS, XPS and AES is a key for understanding.
- Spin polarized photoemission with circularly polarized light (from a synchrotron source)
allows the experimental determination of bandstructure symmetries and of the hybridization between bands.
- Calibration of spin-polarized electron sources
- Spin selective electron diffraction
- Spin dependent metastable deexcitation spectroscopy (MDS)
- Spin resolved electron energy loss spectroscopy (EELS)
- Spin labelling experiments
- Secondary electron microscopy with polarization analysis (SEMPA)
