Design and construction of helical resonators for ion traps

High voltage radio frequency (RF) supply is a critical part in the ion trap system. To predict the resonant frequency of the RF supply for the ion trap, we model the helical resonator and the ion trap as a lumped element circuit. Based on the model we present the construction process of a helical resonator. We measured resonant frequency for different loads. The experimental results are in good agreement with our model.
