摘要

In this paper we discuss recent work to further improve our superconducting (SC) ADS driver linac design. Our design assumes use of the 6.7-MeV LEDA RFQ as an injector to the SC driver linac. We have examined the feasibility of accelerating a 20-mA CW beam to 600 MeV using only 350-MHz SC multi-spoke resonator cavities operating at 4°K. Replacing the 2°K, 700-MHz SC elliptical cavity sections with spoke resonators has several advantages, including reduced cryo-plant operating cost and an improved real-estate accelerating gradient due to the longer active lengths of the 350-MHz cavities. We discuss the details of the new design layout and beam dynamics simulations, including effects due to operational and alignment errors. Preliminary cavity modelling results for the proposed five-gap spoke resonators are also discussed. This accelerator design would be appropriate as a driver linac for applications such as waste transmutation, fusion materials testing, etc.
