Abstract: The purpose of Hefei National Synchrotron Radiation Laboratory (HESYRL)project is to build a dedicated VUV and soft X--ray Synchrotron light source, an800 MeV storage ring with a 200 MeV linac injector. The critical wavelength ofthe Synchrotron radiation from bending magnets is 24 A. The brilliance at 300mA stored beam current can reach 3.48×10~(14) photons/s·mm~2·mrad~2·1% BW. Atotal of 27 photon beam ports, including three ports from insertion devices, canaccommodate photon beamlines. However, only 4 beamlines will be installed andopen to users during the start--up phase of the light source. Two of them coverUV region, while the other two cover soft x--ray region. The construction of the light source is underway. Most of the linac componentshave been completed. The components of the storage ring are being manufacturedin factories. The photon beamlines are in design and prototype phase. Theconstruction of the linac tunnel and klystron gallery are finished. Thestorage ring hall will be completed by the end of this year. The linac installationbegan last summer, and the storage ring installation is scheduled for next year.
