Design of proton beam optics to realize beam distribution transformation in C-ADS HTBT

    Corresponding author: WANG Xiang-Qi,

Abstract: The linac to the transmuter beam transport line (LTBT) connecting the end of the linac to the spallation target is a critical sub-system in the accelerator driven system (ADS). It has the function of transporting the accelerated high power proton beam to the target with a beam footprint satisfying the special requirements of the minor actinide (MA) transmuter. In this paper, a preliminary conceptual design of the hurling magnet to transmuter beam transport section (HTBT), as a part of the LTBT, for the China ADS (C-ADS) system is proposed and developed. In this design, a novel hurling magnet with a two dimensional amplitude modulation (AM) of 1 kHz and scanning of more than 10 kHz at 360° in transverse directions is used to realize a 300 mm diameter uniform distribution of beam on target. The preliminary beam optics design of C-ADS HTBT optimized to minimize the beam loss on the vacuum chamber and the radiation damage caused by back-scattering neutrons will be reported.
