Designing the RF electric core of an ion trap


Analogously to a beating heart, the electrodes of an ion trap need to receive synchronous RF electric signals with a precise frequency and phase in order to function properly. We developed a compact RF drive for the electrodes of our ion trap composed of interdependent RLC circuits resonating at iso-frequency, iso-amplitude and with proper phase opposition. The circuit provides an amplification factor of 200 and it allows ions' micromotion correction via feedback loops.
