我们提出了一种新的用于高精度光谱的单离子端帽陷阱，该陷阱被设计为最大限度地减少离子与环境的相互作用。我们详细地描述了该设计，然后使用单个陷阱来描述工作陷阱的特性。超微运动已被消除，达到了探测方法的分辨率，陷阱显示出异常的声子加热率。还测量了陷阱结构的热性质，测量了离子位置的有效温升。这种陷阱对离子产生的微小扰动使其适合于在电平以下具有部分不确定度的光学频率标准。
We present a new single-ion endcap trap for high-precision spectroscopy that has been designed to minimize ion–environment interactions. We describe the design in detail and then characterize the working trap using a single trappedion. Excess micromotion has been eliminated to the resolution of the detection method, and the trap exhibits an anomalous phonon heating rate of. The thermal properties of the trap structure have also been measured with an effective temperature rise at the ion’s position of. The small perturbations to the ion caused by this trap make it suitable to be used for an optical frequency standard with fractional uncertainties below thelevel.
