Morpheus is the new name for TOPSI, which has been moved from the SAPHIR research reactor to SINQ. Having made several modifications we turned it into a versatile two-axis diffractometer. Reflectometric measurements and simple crystallographic tasks are the domain of Morpheus as well as it is a basis for tests and preliminary measurements in the development of new instrumentation concepts. The instrument is operating since August 7, 1997. Unique possibilities exist for the characterization of neutron optical coatings in conjunction with the polarised beam option implemented in 1998.

A Ultra Small Angle Neutron Scattering (USANS) option is available on Morpheus. For details see ECHO.

The instrument can be used in conjunction with

  • the development of supermirror coatings for neutron guides;
  • quality control of multilayer coatings and polarizers produced at PSI and elsewhere;
  • test of polarizing equipment;
  • sample alignment;
  • the implementation and test of electronic components for neutron spectrometers;
  • feasibility studies for experiments as neutron topo-tomography;
  • tests of prototypes for new instruments as e.g. MARS;
  • ultra small angle neutron scattering (ECHO).
