Abstract :
A radiofrequency system with an active higher-harmonic (“Landau”) cavity may prevent coupled-bunch instabilities and increase the bunch lifetime of an electron storage ring. However, the equilibrium phase and Robinson instabilities must be avoided. An algorithm is presented for evaluating an active Landau cavity, and applied to the electron storage ring, Aladdin
