Research and development for future ERL light sources and construction of the Compact ERL

Abstract

Energy-recovery linac (ERL), which produces a small-emittance beam with high-average current, is a promising device for future light sources. In Japan, we have organized a collaboration team toward future ERL light sources and started R&D efforts to establish accelerator technologies for the ERL light sources. In this paper, we describe status of accelerator components R&D’s and on-going construction of a test facility, the Compact ERL.
