如果不采取应对措施，地面运动效应将使未来直线对撞机的性能恶化到不可接受的水平。与其他已提出的方法相比，一种新的地面运动抑制方法(基于前馈控制)具有改善性能和降低系统成本的潜力。为了对这种前馈方案进行实验验证，在KEK的ATF2上安装了专用的测量装置。本文介绍了这一实验验证的进展情况。前馈方案的一个重要部分已经得到演示，即预测由于地面运动测量而引起的轨道抖动。
Without counter measures, ground motion effects would deteriorate the performance of future linear colliders to an unacceptable level. An envisioned new ground motion mitigation method (based on feed-forward control) has the potential to improve the performance and to reduce the system cost compared to other proposed methods. For the experimental verification of this feed-forward scheme, a dedicated measurement setup has been installed at ATF2 at KEK. In this paper, the progress on this experimental verification is described. An important part of the feed-forward scheme could be already demonstrated, namely the prediction of the orbit jitter due to ground motion measurements.
