论文摘要
低能离子束的2D和4D横向空间用两个最常见的发射扫描仪测量。本文涵盖了两个发射机表的安装，设置，设置，实验和基准的描述。我们比较了三个系列测量结果的结果，并提供了两个系统的优点和缺点。讨论了相位空间平面之间的耦合，相关性和缓解有害影响的耦合。突出显示了背景噪声和痕量空间数字对发射量测量和RMS计算的畸变的影响，尤其是对于低密度梁和光晕。描述了一种新的数据分析方法，使用降低，滤波和重建的降压图。最后，回忆了一些相空间理论和对光束传输的应用的基本概念。
2D and 4D transverse phase-space of a low-energy ion-beam is measured with two of the most common emittance scanners. The article covers the description of the installation, the setup, the settings, the experiment and the benchmark of the two emittance meters. We compare the results from three series of measurements and present the advantages and drawbacks of the two systems. Coupling between phase-space planes, correlations and mitigation of deleterious effects are discussed. The influence of background noise and aberrations of trace-space figures on emittance measurements and RMS calculations is highlighted, especially for low density beams and halos. A new data analysis method using noise reduction, filtering, and reconstruction of the emittance figure is described. Finally, some basic concepts of phase-space theory and application to beam transport are recalled.
