High-beta linac accelerating structure

At the present time the two sets of the typical parameters of the proton high-current high-energy linac are considered. The First one with the beam energy of 1.5 GeV and average current of 0.3 A serves for the transmutation of long-living radioactive wastes of atomic power engineering (ATW program). The second one with the energy of 800 MeV and average current of 10 mA belongs to the conversion program ABC of war plutonium utilization. There are sets of parameters (for example one of Los-Alamos projects: 800 MeV. 140 mA) which occupy intermediate position within the aforementioned limits. The basic problem for all parameter configurations is the selection of accelerating structure for high-energy linac part because this choice influence on linac manufacture. Exploitation and reliability. The D&W accelerating structure invented in MRTI was used in 100-600 MeV energy range for Moscow Meson Facility (MMF). This structure is also preferable for the above designs.<
