The Nuclear Resonance beamline (ID18) is designed and optimized for the excitation of nuclear levels of probe atoms in the sample under investigation. Key parameters are:
- optimized flux at the Mössbauer energies in the range from 7 keV to 30 (80) keV
- high energy resolution down to 0.1 meV level by 'electronic' monochromators
- ultra-high energy resolution down to 10 neV level by 'nuclear' monochromators
- time resolution down to sub-ns level
- use of the pulsed time structure of the synchrotron source
