摘要：

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 (sigma(x)), vertical (sigma(y)), and longitudinal beam sizes (sigma(z)), respectively, for 50 bunch crossings.
