The study suggested that, during the tuning process to compensate for manufacturing errors, some harmonic contents (other than the first ones) should be minimized. The analysis presented in this paper looks at how we can predict the beam quality knowing the content of each voltage harmonics. We propose also a strategy to minimize the impacts of the voltage errors on the output beam phase space during the tuning phase.
