BL-3B : VUV Photoelectron Spectroscopy

Overview

Beamline group Subcommittee 1 (Photoelectron spectroscopy)
Technique
  • Angle-resolved photoelectron spectroscopy
Features
  • The photon-energy range available at BL-3B is 20 - 300 eV for the horizontal linear polarized light.
  • An angle-resolved photoelectron spectroscopy (ARPES) apparatus with a rotating hemispherical analyzer (HA45, a 50-mm radius) is installed.
  • A sample load-lock system, a sample preparation chamber, an Auger electron spectrometer, a low energy electron diffraction optics, and a 5-kV ion gun are available.
Area of research
  • Surface science
Organization
  • Surface science user group
Contacts
