摘要:

对于项目X,计划将每束3x 10 **11个粒子的光束注入主注入器。因此,在8-GeV,将有增加的空间电荷调谐位移和增加的非相干调谐扩展。在准备这些更高强度的聚束探索性研究已经开始在不同的曲调不同强度聚束的传输。描述了一个实验,其结果为20和300 10**9粒子之间的聚束强度。为了实现最高强度聚束在8-GeV是必需的,导致在一个较长的聚束长度。比较表明,当强度和聚束长度分别增加3.2和3.4倍时,得到了类似的透射曲线,表明非相干调谐位移是相似的,正如理论所预期的那样。这些实验的结果将用于结合模拟,以进一步研究主注入器中的高强度聚束。

英文摘要:

For Project X, it is planned to inject a beam of 3x10**11 particles per bunch into the Main Injector. Therefore, at 8-GeV, there will be increased space charge tune shifts and an increased incoherent tune spread. In preparation for these higher intensity bunches exploratory studies have commenced looking at the transmission of different intensity bunches at different tunes. An experiment is described with results for bunch intensities between 20 and 300 10**9 particles. To achieve the highest intensity bunches coalescing at 8-GeV is required, resulting in a longer bunch length. Comparisons show that similar transmission curves are obtained when the intensity and bunch length have increased by factors of 3.2 and 3.4 respectively, indicating the incoherent tune shifts are similar, as expected from theory. The results of these experiments will be used in conjugation with simulations to further study high intensity bunches in the Main Injector.
