Keywords： SR light source

The conceptual of Hefei Advanced Light Source,which is an advanced VUV and Soft X-ray source,was developed at NSRL of USTC.According to the synchrotron radiation user requirements and the trends of SR source development.some accelerator-based schemes were considered and compared;furthermore storage ring With ultra low emittance Was adopted as the baseline scheme of HALS.To achieve ultra low emittance.some focusing structures were studied and optimized in the lattice design.Compromising of emittance,onmomentum and off-momentum dynamic aperture and ring scale,five bend acromat(FBA)Was employed.In the preliminary design of HALS,the emittance Was reduced to sub nm-rad,thus the radiation up to water window has full lateral coherence.The brilliance of undulator radiation covering several eVs to keVs range is higher than that of HLS by several orders.The HALS should be one of the most advanced synchrotron radiation light sources in the world.
