The Protein Crystallography Beamlines at the Pohang Light Source II

Pohang Light Source II (PLS-II) is a 3.0 GeV national synchrotron radiation facility in Korea. Three protein crystallography beamlines at PLS-II are available for national and international users in the structural biology community. All three beamlines (BL-5C, BL-7A and BL-11C) are illuminated with an in-vacuum undulator source, which provides a tunable high brilliant X-ray. BL-5C and BL-7A are designed for routine protein crystallography with a default beam size of 100 µm, while BL-11C is designed for micro-crystallography with a default beam size of 10 μm. This report summarizes the primary parameters of the three beamlines, and describes user productivity and recent experimental results.
