Beam line 6-2b is a wiggler end-station dedicated to micro-focus High Resolution Hard X-ray Spectroscopy using polycapillaries and micro computed tomography. High-Energy Resolution Fluorescence Detected X-ray Absorption Spectroscopy (HERFD-XAS) is performed in a dedicated He environment, with 3 rows of 5 analyzer crystals.

Beamline 6-2a is a wiggler-based versatile experimental station designed for high-energy-resolution spectroscopy in the tender x-ray range (1.6–5.0 keV). The station features a Johansson-type x-ray spectrometer operating on a Rowland geometry with cylindrical Johansson analyzers, enabling sub-natural linewidth energy resolution (~0.32 eV at 2400 eV). This instrument provides the unique capability of performing advanced spectroscopy (XES/HERFD-XAS/RIXS) studies for elements such as S, Cl, 4d metals, and 5f actinides.
