SANS instruments at the Jülich research reactor FRJ-2

A brief description and characterization is given of the three small-angle neutron scattering instruments (SANS) in the new guide laboratory at the Jülich FRJ-2 reactor, namely two 40 m slit-collimation instruments and a very high-resolution double-crystal diffractometer. The combination of the two instruments allows one to cover a range of scattering vectors Q of nearly four orders of magnitude.
