Ensures same spot for all k//
With the new DA30, we are proud to present the world?s first hemispherical analyser using deflectors that enables angular scans in two dimensions in k-space without tilting the sample.
Spin Scan
A major advantage of the MCP/CCD and Spin detection combination is that the parallel angular detection can be used to ensure that the spin-resolved measurement is performed at the desired point in k-space. In the previous Scienta analysers, this has been
acheived by fi rst recording a parallel ARPES spectrum with the MCP/CCD detector and then, without tilting the sample, recording a spin-resolved spectrum for the
center of that spectrum.
With the new analyser concept deflectors have been added. This can be used to record
spin-resolved spectra for all points of the recorded ARPES spectrum. Different lines can of course be combined to cover the whole plane in ?x-E-space.
