However, the large scale of modern light source has limited it from popular use. Compact accelerator light source has many virtues such as small scale, cost effectiveness, maintenance convenience, etc., which make it a main solution of light source application in industry. The idea has attracted great interests from many institutes, and much effort has been put into its research and development. In this paper we present a design of compact accelerator light source with very small scale. The lattice is very simple to ensure its compactness, while the beam parameters remain flexible to industry needs.
