Description
A 1 GeV superconducting proton linac is being proposed as a driver for an accelerator driven system (ADS) for nuclear waste transmutation. In 2014, a compact design for an ADS driver linac based on state-of-the-art Niobium superconducting RF technology was developed at Argonne National Lab. Since then, a new and transformational SRF technology has emerged based on Nb3Sn material. The new technology offers similar performance to Niobium but at higher operating temperatures with the potential of significantly reducing the operation costs of future linac-based accelerator facilities. The goal of this study is to re-design the original ADS driver linac to take advantage of Nb3Sn technology. The accelerating cavity types, operating frequencies and dimensions will be revised. It also involves the physics design of the new linac for efficient acceleration and focusing, and performing end-to-end beam dynamics simulations at full beam energy and current.
