Performance Simulation for a Prototype 1.5 GHz Superconducting Harmonic Cavity

Superconducting radio frequency cavities are used as main accelerating cavities and harmonic cavities in modern light sources. The addition of a harmonic cavity provides the possibility to increase the electron bunch length and therefore to improve the beam life time. The effects on instabilities and the bunch lengthening factor by harmonic cavities can be obtained from theoretical calculations. H...
