TASP occupies the end position of the neutron guide 1RNR14 that has a critical wavelength λmin = 1.7 Å. Some specific features of the instrument are:
- Optional Collimation of the Beam before the Monochromator
- W-configuration Possible for all Accessible Scattering Vectors
- Polarization Capability using HOPG combined with polarising benders
- Vertically Focusing Monochromator
- Horizontally Focusing Analyser
- Neutron Polarimetry using the MuPAD setup
