在保罗阱中捕获离子需要使用谐振器产生的高射频电压。当在低温环境中操作陷阱时,具有低损耗的真空谐振器对于限制低温恒温器的热负荷至关重要。在这项研究中,我们提出了一个设计和生产的指南,紧凑的,屏蔽低温谐振器。我们制作并表征了三种不同类型的谐振器,并进一步证明了这些谐振器在低温下的有效阻抗匹配。
Trapping ions in Paul traps require high radio frequency voltages, which are generated using resonators. When operating traps in a cryogenic environment, an in-vacuum resonator showing low loss is crucial to limit the thermal load to the cryostat. In this study, we present a guide for the design and production of compact, shielded cryogenic resonators. We produced and characterized three different types of resonators and furthermore demonstrate efficient impedance matching of these resonators at cryogenic temperatures.
