给出了加速器实验装置阻尼环在多束团模式下的电子束发射度测量结果。测量是用升级的激光线束轮廓监测器进行的。该监视器现在既有一根垂直导线，也有一根水平导线，由于腔内有效激光功率的增加，能够进行更快的测量。测得的发射度在水平和垂直方向上都没有很大的束对束依赖关系。垂直发射度的值与单束团操作中得到的值相似。本文的结果是实现高能直线对撞机的重要一步。
We present the measurement results of electron beam emittance in the Accelerator Test Facility damping ring operated in multibunch modes. The measurements were carried out with an upgraded laser wire beam profile monitor. The monitor has now a vertical wire as well as a horizontal one and is able to make much faster measurements thanks to an increased effective laser power inside the cavity. The measured emittance shows no large bunch-to-bunch dependence in either the horizontal or vertical directions. The values of the vertical emittance are similar to those obtained in the single-bunch operation. The present results are an important step toward the realization of a high-energy linear collider.
