Abstract:

In this paper, we present the design and optimization of a side-coupled accelerating structure with an energy switch. The beam parameters are optimized, and the electric field asymmetry in the first cell is analyzed. The new structure we designed has an improvement of 10 times in the accelerating field symmetry. Thermo-mechanical analysis is performed based on the electromagnetic results. The highest temperature is 72.5 °C at the nose cone, and the maximal deformation is 73 μm at the outer edge of the coupling cavity.

Key words: Side-coupled accelerating structure, Energy switch, Beam dynamics, Asymmetry, Thermo-mechanical analysis
