Abstract

We describe here the realization and tests of a two stage torsion pendulum facility (nicknamed PETER, from Italian PEndolo Traslazionale E Rotazionale, namely translational and Rotational Pendulum) for the measurement of the Gravitational Reference Sensor (GRS) actuation Cross Talks (CT) for LISA-Pathfinder and its possible evolution. This project started within the ground testing activities for the characterization, before flight, of the GRS of LISA-Pathfinder, where it showed results consistent with what observed on flight. The apparatus could easily evolve to a facility to test small forces/torques on free falling instrumented masses, for future next generation space missions. Here, we will discuss the principle of operation of the double torsion pendulum and the initial goal of the activity, the description of the PETER apparatus, cross -talk measurement technique and results and possible extension to more than 2 DoF

彼得:一个扭摆装置，用来研究自由下落的仪器质量上的小力/力矩

我们在这里描述了用于测量LISA-Pathfinder重力参考传感器(GRS)驱动串扰(CT)的两级扭摆设备(绰号PETER，来自意大利PEndolo Traslazionale E Rotazionale，即平移和旋转摆)的实现和测试及其可能的发展。该项目开始于LISA-Pathfinder的地面测试活动，在飞行前对GRS进行表征，其结果与飞行中观察到的结果一致。该设备可以很容易地发展成一个设备，以测试自由下落的仪器质量上的小力/扭矩，用于未来的下一代太空任务。在这里，我们将讨论双扭摆的工作原理和活动的初始目标，PETER装置的描述，串扰测量技术和结果，以及可能扩展到超过2自由度
