SANS-1

Small angle neutron scattering instrument

This instrument is focussed on cold neutrons. All parameters given here are valid during the current operation of FRM II. Please get in touch with the instrument team well in advance for all further details (length of experiment etc.).

Insrumentscheme SANS-1 Insrumentscheme SANS-1

SANS-11 is a standard pinhole instrument with 23 m collimation distance and 20 m sample detector distance. SANS-1 uniquely features two velocity selectors with minimum 10 % and 6 % Δλ/λ. A wavelength band from 3.45 – 6 Å is usable and by using the option of tilting the selectors, the flux increases to 20 % Δλ/λ. A key feature is the large accessible dynamic Q-range facilitated by the sideways movement of the primary 1m2 detector, particularly for single shot measurements.

SANS-1 features a flexible, spacious sample stage equipped with a heavy-duty goniometer, allowing a wide range of different sample environment. The sample goniometer carries various loads up to 900 kg and fulfils the rising demand on diffraction experiments at low scattering angles, e.g., for studies of superconducting vortex lattices and other large magnetically ordered systems.
