SpAnTeX

Spectroscopic Analysis with Tender X-Rays

The SpAnTeX instrument is dedicated to in situ Spectroscopic Analysis with Tender X-rays in order to obtain detailed chemical composition information about solid/liquid interfaces for new, improved materials. Its molecular-level information about semiconductor/electrolyte interfaces should aid the rational design and optimization of the next generation of energy materials. Additionally, the wide pressure and photon energy range covered by the SpAnTeX instrument will enable investigations of solid/solid, solid/gas, liquid/vapor and liquid/liquid interfaces as well.

Please note:

The SpAnTeX endstation will be placed permanently at the BElChem-DCM beamline as soon as the beamline is ready. Until then, SpAnTeX is operated with limited time at the KMC-1 beamline.

The SpAnTeX will operate within the Berlin Joint Lab for Electrochemical Interfaces (BElChem) which is located at the BESSY II synchrotron in Berlin, Germany, and co-run by the Fritz-Haber-Institut, the Max-Planck-Institut of Chemical Energy Conversion and the Helmholtz-Zentrum Berlin. BElChem focuses on providing a molecular-level description of (photo)electrochemical interfaces that are of high relevance for solar fuel production and renewable energy storage.

The BElChem facility consists of two beamlines (BElChem-PGM for soft X-rays and BElChem-DCM for tender X-rays) with two endstations in two separate hutches and an additional sample preparation/chemical lab.
