Berlin Joint Lab for Electrochemical Interfaces @Dipole
The BElChem-DCM beamline covers the tender X-ray energy range from approximately 2.4 to 10 keV with a double crystal monochromator containing a Si(111) crystal pair. Its source is the dipole bending magnet D4.2. The optical elements and layout of the beamline have been optimized to deliver a high photon flux over a broad energy range, in particular at energies up to 8 keV, with moderate spectral resolution. This helps to facilitate in-situ and operando experiments that are conducted at elevated gas pressures or in liquids.

The Berlin Joint Lab for Electrochemical Interfaces (BElChem) 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 with two endstations in two separate hutches and an additional sample preparation/chemical lab. BElChem-PGM (plane grating monochromator) covers the soft X-ray energy range, whereas BElChem-DCM (a dipole magnet sourced beamline) with a double crystal monochromator (DCM) covers the tender X-ray energy range.
