针对HMBA（混合多弯消色差）型最先进光源的设计研究，新型存储环是根据ESRF二期升级项目（ESRF II）的晶格设计的。尽管ESRF Pantaleo Raimondi博士的原始3 GeV测试晶格在包括动态孔径在内的光磁参数方面没有问题，但我们减少了单元数量并为真空短间隙波荡器插入了短直段。以线性和非线性光学作为ESRF II的原始设计原理进行优化后，改变的晶格周长约为440 m，具有16个HMBA单元，发射度约为440 pm rad，在束流500 mA时具有束内散射效应，即使在通常的磁误差下，注入点处也具有约2 cm的大动态孔径。
For the design study of the HMBA (hybrid multi bend achromat) type most advanced light source, the new storage ring was designed from the lattice of the phase II upgrade project of the ESRF (ESRF II). Although the original 3 GeV test lattice from Dr. Pantaleo Raimondi of ESRF has no problem about the optical and magnetic parameters including the dynamic aperture, we reduce the cell numbers and inserted the short straight sections for the in-vacuum short-gap undulators. After the optimization of the linear and non-linear optics as the original design principle of ESRF II, the altered lattice has the circumference of about 440 m with 16 HMBA cells, the emittance about 440 pm rad with the intra-beam scattering effect at the beam current of 500 mA, and the large dynamic aperture of about 2 cm at the injection point even with the usual magnetic errors.
