Beamline 10.0.1 Home Page

In addition to the central branch, where no horizontal deflecting mirror is used, the beamline counts with two side branches by use of the horizontal deflecting mirrors schematically shown in Figure 1. One of these side branches is dedicated to the High Energy Resolution Spectrometer (HERS) endstation, designed for angle-resolved photoemission experiments on highly correlated electron systems in condensed matter. The central branch and the other side branch are used to study highly correlated systems in the gas phase. Three of the advanced experimental endstations used on these branches are:

(1) the collinear Ion-Photon Beamline (IPB) endstation
(2) the High-Resolution Atomic and Molecular Electron Spectrometer (HiRAMES), and
(3) the Electron Spin Polarization (ESP) endstation.

The photon-beam source of Beamline 10.0.1 is a 4.55-m-long, 10-cm-period undulator with 43 full periods. The beamline is equipped with a Spherical Grating Monochromator (SGM) (gratings; 380, 925, 2100 lines/mm) that covers the energy range from 17 eV to 340 eV. This beamline provides an intense beam of photons at very high spectral resolution. Over most of its photon energy range, the beamline can deliver more than 10¹² photons/s to the sample at resolving powers (E/ΔE) exceeding 10,000. At the expense of resolution, up to 10¹⁴ photons/s can be obtained over some of this energy range. Alternatively, experimenters can achieve very high resolving power (~64,000) by reducing the monochromator slits and hence the photon flux. Figure 1 shows a schematic layout of the beamline. For further details of the optical design of the beamline, its functionality and calibration procedures go to the Beamline Manual.
