我们使用 7 结电子泵作为电子计数器，每个泵浦电子的误差为 10(9) 中的 15 个部分，平均保持时间为 600 秒。精度和保持时间足以实现新的电容基本标准。我们将作为抽速和温度函数的泵的测量精度与基于包含杂散电容的模型的理论预测进行比较。 (C) 1996 年美国物理研究所。
We have operated a 7-junction electron pump as an electron counter with an error per pumped electron of 15 parts in 10(9) and an average hold time of 600 s. The accuracy and hold time are sufficient to enable a new fundamental standard of capacitance. We compare the measured accuracy of the pump as a function of pumping speed and temperature with theoretical predictions based on a model which includes stray capacitance.
