3D-VLEED - 2D-CMOS/-CCD Detector
Combinded 3D Spin Detector based on the VLEED principle with 2D CMOS detector for high performance ARPES and Spin detection.
3D Spin detection combined with full scale 2D APRES measurements provide a deep understanding of the electronic structure of spin polarized solids. The combination of the existing high performance 2D detection systems with power spin detectors and optics, allow measurements of the electronic structure on a new level.
The 2D-CMOS/3D Spin VLEED detector uses the VLEED detection scheme for the spin detection. A magnetized iron oxide film is used as a spin selector based on exchange scattering. The VLEED detection scheme can detect 1 channels simultaneously, however with very high speed per channel.
With the patented spin rotator and 90°deflector scheme, all three spin components from the sample can be analyzed. The 90° deflector allows access the one out of plane spin component and the spin rotator switches the detectable in plane component to measure all components in subsequent measurements. The angular range can be refined by using integrated entrance apertures. An additional full scale 2D CMOS detector on the energy dispersive axis is used to acquire APRES data on the same angular region as the spin detector channel.
