Fiber diffraction is one of the techniques used to determine the biology structures of biological molecules such as silk, chitin, amyloidal, proteins and muscle ... etc. The correlation between structures and bio-functions could be obtained from these studies. We provide two dimensional detector such as imaging plate which can collect data within reasonable time. To apply external fields on these samples are also possible to perform at this beamline such as magnetic field, electric field, pressure, and light induced.
