The Japan Atomic Energy Agency (JAEA) is currently focused on the research and development of a 30-MW continuous wave (CW) proton linear accelerator (linac) designed for the JAEA accelerator-driven subcritical system (ADS). The linac uses superconducting cavities to accelerate a 20 mA proton beam to 1.5 GeV. The beam is then directed to a spallation target, producing neutrons for a subcritical 800-MWth reactor. The main challenge for an ADS accelerator is the high reliability required to prevent thermal stress in the subcritical reactor. Therefore, our objective is to establish a strong lattice structure in order to ensure stable operation and enhance the availability of the linac by minimizing beam downtime through the implementation of local compensations for element failures. This presentation will cover the beam optics design strategy for the linac and discuss the results of beam dynamics studies of the JAEA-ADS linac.
