NE3A X-ray Beamline for High-throughput Macromolecular Crystallography
NE3A is deigned for high-throughput macromolecular crystallography which is applied in pharmaceutical researches. Using double crystal monochromator cooled with liquid nitrogen, a wide energy range (6.5 - 17 keV) of the the monochromatic beam is available with fine energy resolution. A high-precision (SOC is less than 2 micron) sample axis allows experiments with micro-crystals. A robot for sample exchange will be installed to improve the efficiency of experiments.
