摘要
我们报告了在欧洲空间局 LISA Pathfinder 任务上进行的静电测量。在电容式引力参考传感器内对作用于自由落体测试质量(TMs)的电荷诱导静电力所做的详细测量，是在天基引力波探测器的相关环境中进行的首次测量。采用电荷控制与电场补偿相结合的方法，我们表明单个 TM 上的电荷诱导加速度噪声水平在 0.1-100 mHz 频率带内可维持在接近 1.0 fm/s^2/sqrt(Hz) 的水平，该频带对 LISA 这类观测站至关重要。利用专门测量来探测两个测试质量之间差分加速度中的这些效应，我们分辨出由于行星际宇宙射线导致的 TM 电荷累积的随机性质，以及通过传感器中杂散电场的 TM 电荷-力耦合。我们所有的测量结果与基于 LISA Pathfinder 仪器相对简单的静电模型的预测非常吻合。
