Abstract

To determine the maximum accelerating gradient and thus the length of a future multi-TeV electron-positron linear collider, one has to know the breakdown limit in any accelerating structure. A special accelerating structure has been designed for testing up to accelerating gradients of 300-350 MeV/m using the 45 MW, 34.3 GHz pulsed magnicon amplifier. The 2π/3, 57 mm-length accelerating structure contains 19 cells and operates in standing wave (SW) mode in order to achieve maximum surface electric field
