叙述了第三代同步辐射光源ＨＥＬＳ的设计研究，包括１台能量为７ＧｅＶ的光源储存环，１台７ＧｅＶ的电子同步加速器注入器和１台４５０ＭｅＶ的电子直线加速器预注入器。光源储存环的束流发射度达到２．３３ｎｍ·ｒａｄ，是目前世界上现有的同样能量的光源储存环的发射度的三分之一左右。从储存环的插入元件波荡器（Ｕｎｄｕｌａｔｏｒ）引出的同步光的亮度达到１０２０（即在ｓ－１·ｍｍ－２·ｍｒａｄ－２／０．１％带宽内的光子数），比目前国际上同样能量光源的亮度高１～２个数量级。
Describes the design and research of the third generation of synchrotron radiation source HELS, including a 7GeV light source storage ring, a 7GeV electron synchrotron injector and a 450MeV electron linear accelerator pre-injector. The beam emission of the light source storage ring reaches 2.33 nm · rad, which is about one third of that of the existing energy storage ring of the same energy in the world. The brightness of the sync light derived from the Undulator inserted into the storage ring reaches 1020 (ie, the number of photons in the s-1 · mm-2 · mrad-2 / 0.1% bandwidth) The energy of high brightness light source 1 to 2 orders of magnitude.
