The CXS beamline is located at the port 25 of TPS. The port 25 is an output port of a 12-meter long straight section where two IU22 undulators, a 3 meter-long IU22 undulator and a 2 meter-long IU22 undulator, are is installed. at a long straight section. The photon source of CXS beamline is irradiated from the two in-vacuums undulators IU22, which provide the X-rays beam with the energy range from 5.56 to 20 keV, based on the 3rd, 5th, 7th, 9th, or 11th harmonic of IU22.

The estimated photon flux, brilliance and coherent photon flux are shown as the following figures.
