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 two-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.

我们描述了由一堆精密加工的石英玻璃晶片制成的三维 Paul 离子阱的实现，其中包含一对用于二维离子传输的结。该阱有 142 个专用电极，可用于定义多个可容纳离子串的势阱。通过提供随时间变化的电位，这也允许离子串的传输和重新配置。我们描述了陷阱的设计、模拟、制造和封装，包括对不同参数机制的探索以及可能的优化和设计选择。我们给出了陷阱的初始测试结果，包括加热速率和结传输的测量结果。
