Comparison of accelerating structures driven by stored energy

Comparative analysis of 4 most widely used types of linear accelerating structures operating in a mode, when the energy preliminary stored in them is partially extracted by a bunch sequence, is carried out. Two travelling wave structures are considered: iris-equipped waveguides with phase shift to π/2 and 2π/3 cell and two standing wave structures: one with latteral-coupled resonat cavities and the other with washers and diaphragms. In comparison of accelerating structures main attention should be paid to the following parameters: the necessary power of RF-generator, stored energy, electric strength and efficiency of structure filling with energy. 3 refs.; 5 figs
