SOL³PES

Liquid Jet Ambient Pressure Photoelectron Spectroscopy

The experimental station SOL3PES is  a state-of-the-art experimental setup to study solid, solution and solar-cell systems by soft X-ray photoelectron spectroscopy. It is equipped with a high-transmission hemispherical HIPP-2 R4000 ScientaOmicron electron analyzer for detecting electrons emitted from small molecular aggregates, nanoparticles, or biochemical molecules and their components in (aqueous) solutions, either in vacuum or in an ambient pressure environment. In addition to conventional energy-resolved electron detection, SOL3 enables detection of electron angular distributions by the combination of a ±11° acceptance angle of the electron analyzer and a rotation of the analyzer in the polarization plane of the incoming synchrotron-light beam.
