Overview of fusion-like neutron sources based on high-intensity linear accelerators

Abstract

A dedicated linear accelerator for continuous wave (CW) D+ beams to generate fusion-like neutrons is crucial for the breeding blanket module tests and fusion material irradiation experiments. In this article, we introduce the world-wide activities for such accelerator facilities. Then, we present the case study, pre-conceptual design, and major component specification overview for developing a linear accelerator that could provide the modest beam parameters (40 MeV, maximum 10 mA CW) for breeding module tests. We look into the specifications of the facility and prepare a layout of the envisioned accelerator, which could be aligned with the Korean domestic fusion program. We also carry out the preliminary beam dynamics/optics calculations and operation scenario development.
