| 英文摘要 | In the lattice design of a diffraction-limited storage ring (dlsr) consisting of compact multi-bend achromats (mbas), it is challenging to simultaneously achieve an ultralow emittance and a satisfactory nonlinear performance, due to extremely large nonlinearities and limited tuning ranges of the element parameters. nevertheless, in this paper we show that the potential of a dlsr design can be explored with a successive and iterative implementation of the multi-objective particle swarm optimization (mopso) and multi-objective genetic algorithm (moga). for the high energy photon source, a planned kilometer-scale dlsr, optimizations indicate that it is feasible to attain a natural emittance of about 50 pm.rad, and simultaneously realize a sufficient ring acceptance for on-axis longitudinal injection, by using a hybrid mba lattice. in particular, this study demonstrates that a rational combination of the mopso and moga is more effective than either of them alone, in approaching the true global optima of an explorative multi-objective problem with many optimizing variables and local optima. |
