Energy-recovery linac (ERL) is a promising device for future X-ray light sources. In Japan, we organized a Japanese ERL collaboration team, consisting of the members of KEK, JAEA, ISSP and other laboratories, and then, started R&D efforts for the future ERL light source. In order to demonstrate accelerator technologies relevant to the ERL light source, we have decided to build a small facility, Compact ERL. This report presents a design study of the Compact ERL, which includes R&D issues for each accelerator component, studies on beam dynamics, performance of the Compact ERL as a light source of THz and X-ray.
