Cryogenic resonator design for trapped ion experiments in Paul traps

摘要

Trapping ions in Paul traps requires high radio-frequency voltages, which aregenerated using resonators. When operating traps in a cryogenic environment, anin-vacuum resonator showing low loss is crucial to limit the thermal load tothe cryostat. In this study, we present a guide for the design and productionof compact, shielded cryogenic resonators. We produced and characterized threedifferent types of resonators and furthermore demonstrate efficient impedancematching of these resonators at cryogenic temperatures.
