Comparison of Beam Dynamic in Different Superconducting Options of Low Energy High Intense Linac

At present the superconducting proton linacs have obvious applications in energy range ∼ 100-1000 MeV. For the lower energy < 100 MeV the comprehensive investigations are required. In this article the various variants of superconducting options from 3MeV up to 40-100MeV are discussed. The considered variants include both the conventional combination of half-wave and spoke cavity with quadrupoles and new schemes. In conclusion major parameters for different structures are discussed.
