BL-5A X-ray Beamline for High-throughput Macromolecular Crystallography

BL-5A is deigned for high-throughput MAD experiments with high-flux beam and a rapid data acquisition system. The wide active area of the CCD detector is particularly suited for measurements of crystals with large unit cell dimensions. A high-precision sample axis allows experiments with micro-crystals. A robot for sample exchange will be installed to improve the efficiency of experiments.
