The cold triple-axis spectrometer (TAS) FLEXX at HZB was a well-designed and upgraded instrument. There is a strong wish that this excellent instrument should be preserved for the community. One attractive option in the present instrumentation suite of MLZ, is the possibility to combine high magnetic fields together with cold TAS as well as the Larmor-diffraction technique and cold neutron...
TOPAS is a thermal neutron time-of-flight spectrometer with polarization analysis option, being constructed and commissioned in the MLZ Guide Hall East. We present recent developments as well as future plans for hot commissioning, science, sample environment and user operation.
