Development Of A Radioactive Nuclides Accelerator At The Moscow Meson Factory

A description is presented of the primary proton beam of the meson factory, which is being developed in order to obtain, separate, and accelerate online radioactive isotopic ions up to an energy of 6.5 MeV/amu at an intensity up to 10/sup 12/ atoms/s. In order to accelerate the radioactive beam with an initial ratio of q/A>1/60 with good efficiency, the heavy ion CW linac is considered. It consists of two types of accelerating structures: a 27.12 MHz RFQ at the energy range from 1 keV/amu to 60 keV/amu and the IH structure from 60 keV/amu to a final energy of 6.5 MeV/amu. The operating frequencies of the IH structure are 54.24 MHz and 108.48 MHz.<>
