RCH-2: The Diffraction and Emission Spectroscopy Hutch
Please note: experiments with radionuclides are currently possible only within the general ESRF limits. RCH-2 will be converted into a nuclear experimental station with the same limits as in RCH in 2018.
The core equipment is a six-circle goniometer and a Pilatus-2M dedetcor for diffraction experiments, and a 5-crystal Johann-type emission spectrometer for high-resolution XANES and XES measurements.
