摘　　要：我国最近立项建设的合肥先进光源将是一台软X射线与真空紫外衍射极限储存环光源,其电子束能量为2.2 GeV,周长为480 m,束流自然发射度为86 pm·rad,共有20个长直线节和20个短直线节。介绍了目前合肥先进光源储存环物理设计的进展情况,包括磁聚焦结构设计与优化,束流注入和集体效应的模拟与计算。The Hefei Advanced Light Facility(HALF) is a soft X-ray and VUV diffraction-limited storage ring light source, and the construction of HALF has just been approved by the Chinese government. The electron beam energy of the HALF storage ring is 2.2 GeV;the circumference is 480 m;the natural beam emittance is 86 pm·rad;and there are 20 long and 20 short straight sections in total. This paper will report the physics design progress of the HALF storage ring, including lattice design and optimization, simulation and calculation of beam injection and collective effects.
