FlexPES
The FlexPES (Flexible PhotoElectron Spectroscopy) beamline caters for the experimental needs of both Surface/Material Science and Low Density Matter user communities offering the possibility to perform a variety of photoemission and soft X-ray absorption experiments in the photon energy range 40 – 1500 eV. The two-branch configuration with double-striped toroidal refocusing mirrors ensures maximum flexibility – up to four endstations can be accommodated on the two branches of the beamline simultaneously, and each of these endstations can avail of different focusing conditions. The end stations offer a diverse range of experimental techniques, detectors and sample handling facilities and can be used with a variety of sample delivery systems.
Techniques (as available by Q1 2020)
| Available for | Technique/facility description |
|---|---|
| General Users | Beamline: Linear horizontally polarized light from LPU, with energy range 40-1500 eV. Spot on sample both defocused (0.5-1.5 mm) and focused (from 50x15 um to 150x40 um in different end stations). |
| General Users | Surface- and Material Science (SMS) branch: High-resolution photoelectron spectroscopy (PES) on solid samples using SES-2002 analyzer and 4-axis manipulator; X-ray absorption spectroscopy (XAS or NEXAFS) using total and partial electron yield. |
| General Users | Low Density Matter (LDM) branch: High-resolution PES on LDM samples using R4000 analyzer with the following sample delivery systems (samples must be approved by chemical safety group): - Liquid jet setup for e.g. aqueous solutions - Molecular jet source (continuous beam) for experiments on cold beams of atomic and molecular gases - Gas cell for PES experiments on atomic and molecular gases |
