Disk chopper time-of-flight spectrometer IN5
Disk chopper time-of-flight spectrometer
IN5B is a high precision direct geometry Time-of-flight (ToF) spectrometer. It is used to study low-energy transfer processes as a function of momentum transfer.
Typically this instrument is used for measurements in the small energy and momentum transfer region with values of about 1 % for the energy resolution (e.g. quasi-elastic scattering in solids, liquids, molecular crystals and inelastic scattering with small energy transfers in the range 10 µeV - 100 meV).
- Local and long-range diffusion in disordered systems such as liquids, molecular crystals, amorphous solids (superionic glasses, orientational glasses, spin glasses), polymers, hydrogen-metal systems, ionic conductors
- Dynamics of ’soft matter’, including gels, proteins and biological membranes
- Dynamics of quantum liquids
- Rotational tunnelling in molecular crystals
- Crystal field splitting
- Spin dynamics in high-TC superconductors
- Critical scattering phenomena in dense gases and solids
This shows how the 6 choppers are distributed in the primary spectrometer and how the huge detector bench is designed.
