【摘要】 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。更多还原

【Abstract】 The paper discribes design study of third generation synchrotron radiation light source, high energy light source (HELS). It includes a light source storage ring of 7 GeV, an electron injector synchrotron of 7 GeV and a preinjector linac of 450 MeV. The beam emittance of the storage ring is 2.33 nm·rad , that is about one third of the existing light source of similar energy in the world. The brilliance of the synchrotron radiation from undulators can reach 10 20 (photons·s -1 ·mm -2 ·mrad -2 /0.1 %BW); 1～2 orders higher than the existing light sources.更多还原
