在国际直线对撞机上，测量相互作用点的束流轮廓是实现高亮度的关键。我们报告了一个新的束流剖面监测器，称为对监测器，它使用的碰撞分布的电子-正电子对产生的相互作用点的模拟研究。对于50个束团交叉点，水平（σx）、垂直（σy）和纵向束流尺寸（σz）的测量精度分别为5.1%、10.0%和4.0%。
At the international linear collider, measurement of the beam profile at the interaction point is a key issue to achieve high luminosity. We report a simulation study on a new beam profile monitor, called the pair monitor, which uses the hit distribution of the electron–positron pairs generated at the interaction point. We obtained measurement accuracies of 5.1%, 10.0%, and 4.0% for the horizontal (σx), vertical (σy), and longitudinal beam sizes (σz), respectively, for 50 bunch crossings.
