Abstract Human research on the m icrocosm is the m otive force beh ind the developm ent of particle accelera-
tors, which have been advancing towards higher lum inosity and better perform ance. A long w ith deeper progress in
research, accelerators have moved step by step from low to high energy, from w eak to strong focusing and from
fixed target to beam collision. H igher energy and h igher lum inosity are two frontiers of accelerators for particle
physics. A sm ultidisc ipline platform s, synchrotron radiation fac ilities, free electron lasers and spallation neutron
sources have been developing rapidly. A variety o f low-energy accelerators have been applied throughout a w ide
range of the econom y. N ew m ethods, new technolog ies and new principles have em erged in an endless stream.
T he international frontiers of particle accelerators are des
