SAXS
GANESHA
SAXS and WAXS Laboratory Beamline equipped with a Ga-Metal-jet X-ray source and EIGER 4M single photon counting detector. The main focus of the instrument is to be very versatile and flexible in terms of sample environments and covered q-ranges. Having a Metal-jet source with its high intensity and brilliance enables us to measure all samples in air. The evacuated tube holding the movable detector can be shifted along the beam path to vary the available sample area from a few millimeters up to ∼1m.

The applications range from polymers to biology or liquids and are limited to the scattering vector range given by the wavelength of the xray. Powerful combinations arise if both neutron and xray scattering are applied to the same system, exploiting the full contrast program. The scattered beam contains 3dimensional information on the spatial structure.
