Nanostar is equipped with a microfocus X-ray source with Cu radiation and a VÅNTEC-2000 Xenon-based gas detector. The longest sample to detector distance (160 cm) is used for high-resolution experiments while wide angle studies are also possible at short SDDs. The system uses a semi-transparent beam stop enabling perfect background subtraction and a high resolution for such a lab-based system.
