摘要:

在费米实验室Tevatron的900 GeV研究中首次观察到亮度驱动的沟道提取。这个实验,费米实验室E853,证明了有用的TeV级的光束可以从超导加速器在高光度对撞机操作过程中提取,而不会过度影响在对撞机探测器的背景。发现多转萃取显著提高了该过程的效率。光束提取效率约为25%。时间相关效应的研究发现,匝间结构主要由加速器束流动力学。使用加速器飞线系统的预散射器的研究表明,光纤可以产生显著的提取通量,与预期一致。基于这些结果,从Tevatron对撞机上构造5-10 MHz的寄生质子束是可行的。

英文摘要:

Luminosity-driven channeling extraction has been observed for the first time in a 900 GeV study at the Fermilab Tevatron. This experiment, Fermilab E853, demonstrated that useful TeV level beams can be extracted from a superconducting accelerator during high luminosity collider operations without unduly affecting the background at the collider detectors. Multi-turn extraction was found to increase significantly the efficiency of the process. The beam extraction efficiency was about 25%. Studies of time dependent effects found that the turn-to-turn structure was governed mainly by accelerator beam dynamics. An investigation of a pre-scatterer using the accelerator flying wire system showed that a fiber could produce a significant extracted flux, consistent with expectations. Based on these results, it is feasible to construct a parasitic 5-10 MHz proton beam from the Tevatron collider.
