Abstract :
A new type of display-type spherical mirror analyzer has been constructed at BL25SU of SPring-8 to study atomic arrangement on surface and spin arrangement on magnetic surface, and to analyze the atomic orbital of the electrons constituting the valence band and the other interesting electron spectroscopy. The advantage of this analyzer is that the emitted photoelectrons are converged to a focal point with keeping both kinetic energy and momentum. Hence we can realize energy and momentum analyses at once. To perform these studies accurately, the display-type spherical mirror analyzer should satisfy the following specifications such that the energy resolution should be higher than 1% of the pass-energy and the angular resolution should be higher than 1° at least. The improvement was estimated by LEED and photoelectron diffraction of Si(0 0 1). Finally, we could confirm that the energy resolution is 0.2% of the pass energy and the angular resolution is 0.6°. We conclude that the new analyzer satisfy the above requirement.
