Abstract
A new type of display-type spherical mirror analyzer has been constructed a t BL25SU of SPring-8 to study atomic arrangement on surface and spin arrang ement on magnetic surface, and to analyze the atomic orbital of the electro ns constituting the valence band and the other interesting electron spectro scopy. The advantage of this analyzer is that the emitted photoelectrons ar e converged to a focal point with keeping both kinetic energy and momentum. Hence we can realize energy and momentum analyses at once. To perform thes e studies accurately, the display-type spherical mirror analyzer should sat isfy the following specifications such that the energy resolution should be higher than 1% of the pass-energy and the angular resolution should be hig her than 1 degrees at least. The improvement was estimated by LEED and phot oelectron diffraction of Si(001), Finally, we could confirm that the energy resolution is 0.2% of the pass energy and the angular resolution is 0.6 de grees. We conclude that the new analyzer satisfy the above requirement. (C) 2001 Elsevier Science B.V. All rights reserved.
