摘要：
我们描述了一个三维的保罗离子阱的实施从一堆精密加工的石英玻璃晶片，它采用了一对二维离子传输的结制造。阱具有142个专用电极，其可用于限定多个势阱，其中可保持离子串。通过提供随时间变化的电势，这也允许离子串的传输和重新配置。我们描述的设计，模拟，制造和包装的陷阱，包括探索不同的参数制度和可能的优化和设计选择。我们给出了初步测试的陷阱，包括测量的加热速率和结运输的结果。
英文摘要：
We describe the implementation of a three-dimensional Paul ion trap fabricated from a stack of precision-machined silica glass wafers, which incorporates a pair of junctions for 2-dimensional ion transport. The trap has 142 dedicated electrodes which can be used to define multiple potential wells in which strings of ions can be held. By supplying time-varying potentials, this also allows for transport and re-configuration of ion strings. We describe the design, simulation, fabrication and packaging of the trap, including explorations of different parameter regimes and possible optimizations and design choices. We give results of initial testing of the trap, including measurements of heating rates and junction transport.
