AXIS Supra photoelectron spectrometer

The AXIS Supra (Kratos Analytical) photoelectron spectrometer is based on the proven Axis technology comprising magnetic and electrostatic transfer lenses, co-axial electron charge neutralization system, spherical mirror and hemispherical electron energy analysers. As the primary excitation source monochromated Al x-ray radiation is used. The electron energy analyzer provides both high energy resolution and high sensitivity spectroscopic performance. The chemical state images are collected with less than 10 µm spatial resolution. The charge neutralization system helps to compensate charge on insulation materials. Ar+ gas cluster ion source is attached to the spectrometer for sample cleaning and depth concentration profiling.
