论文摘要
有害束动力学影响高强度快速循环同步子（RC）的限制性能，例如8 GEV Proton Fermilab助推器。在这里，我们报告了助推器中各种梁强度效应的全面实验研究的结果。在第一部分中，我们报告了增强束强度损失的依赖性对每个脉冲质子总数以及关键操作参数（例如机器调音和色素）的依赖性。然后，我们交叉检查梁发射测量值的两种方法（多线比例室和电离轮廓监测器）。最后，我们使用了依赖强度的发射率生长效应来分析机器在当前配置中的最终性能，最大空间充电的TUNESHIFT参数QSC为0.6，在其注入能量后，将其注入能量从0.4 GEV升级到0.8 GEV。
Detrimental beam dynamics effects limit performance of high intensity rapid cycling synchrotrons (RCS) such as the 8 GeV proton Fermilab Booster. Here we report the results of comprehensive experimental studies of various beam intensity dependent effects in the Booster. In the first part, we report the dependencies of the Booster beam intensity losses on the total number of protons per pulse and on key operational parameters such as the machine tunes and chromaticities. Then we cross-check two methods of the beam emittance measurements (the multi-wires proportional chambers and the ionization profile monitors). Finally we used the intensity dependent emittance growth effects to analyze the ultimate performance of the machine in present configuration, with the maximum space-charge tuneshift parameter Qsc of 0.6, and after its injection energy is upgraded from 0.4 GeV to 0.8 GeV.
