Construction and Evaluation of Coaxially Symmetric Mirror Electron Energy Analyzer with High Sensitivity, and Its Application to Coincidence Spectroscopy

Development of New Apparatus for Electron–Polar‐Angle‐Resolved‐Ion Coincidence Spectroscopy and Auger–Photoelectron Coincidence Spectroscopy

“…Further information on EICO studies of surfaces is available at the homepage of http://pfwww.kek.jp/eico/EICO.html. In this review we describe details of the latest (fourth) EICO analyzer [14,46] in Section 16.2 and a new electron-polar-angle-resolved-ion coincidence analyzer [47] in Section 16.3.…”

“…Although the CMA is compact (26 mm×71 mm), it has a wide solid angle of 0.72 sr. We report the details of the APECS apparatus and the result of its application to the Si LVV Auger-Si 2p photoelectron coincidence spectrum of a clean Si(111) surface in the following sections. [47] and (b) a photograph [46]. OD stands for outer diameter.…”

“…The analyzer, however, had a weak point in that the performance was degraded by the disturbance of the electric field near the end plates. We have improved their analyzer and developed a modified one, which consists of an inner electrode, an outer electrode, three sets of compensation electrodes, a pinhole with a diameter of 0.8 mm, microchannel plates (MCP, Hamamatsu Photonics, F4655), and a magnetic shield(Figures 16.2 and 16.3)[46]. The trajectories of electrons and isoelectric lines simulated with SIMION 3D version 7.0 (http://www.sisweb.com/simion.htm) are also shown inFigure 16.2.…”
