Microfabricated ion-trap devices offer a promising pathway towards scalable quantum computing. Addition of on-chip features, however, increases the power dissipated by components such as current-carrying wires and digital-to-analogue converters (DACs). Presented here is the development of a modular cooling system designed for use with multiple ion-trapping experiments simultaneously enabling efficient cooling to 70K while provide significant and scalable cooling power.
