我们描述了一种新型的电子束轮廓监测仪，用于测量尺寸小至10 μ m的电子束。该监视器是基于电子与激光靶的康普顿散射。将连续波激光束注入法布里-珀罗光腔，产生细而强的激光束（激光线）。我们能够获得稳定的激光线，束腰为14.52±0.55µm，功率增益为220±20。该监测仪安装在KEK的ATF阻尼环中，用于测量其垂直发射度。本文详细介绍了该监测仪的研制和性能研究。
We describe a new type of beam profile monitor developed for measurements of an electron beam as small as 10 µm in size. This monitor is based on the Compton scattering of electrons with a laser light target. A thin and intense laser beam (laser wire) is produced by injecting a CW laser beam into a Fabry–Perot optical cavity. We were able to obtain a stable laser wire having a beam waist of 14.52±0.55 µm and a power gain of 220±20. This monitor was installed in the ATF damping ring at KEK, and was used to measure its vertical emittance. We report in this paper the development and performance studies of this monitor in detail.
