摘要

未来环形电子-正电子对撞机（FCC-ee）的设计旨在推动轻子对撞机在能量和光度方面的发展。这就要求管理前所未有的高强度轻子束流，存储束流能量高达 17.5 兆焦耳。因此，光束准直系统不仅对于控制实验背景至关重要，而且对于安全处理不可避免的光束损失和确保机器的可用性也至关重要。准直系统设计所面临的独特挑战亟待解决，而在弯曲晶体辅助准直方案中利用带电粒子通道作为提高准直性能的一种可能解决方案正在探索之中。本文介绍了首次评估在 FCC-ee 中实施这种准直方案可行性的研究。

First studies of crystal collimation for the FCC-ee

The Future Circular electron–positron Collider (FCC-ee) is being designed to push the energy and luminosity frontiers for lepton colliders. This requires managing unprecedented intensities of lepton beams, with stored beam energies up to 17.5 MJ. Therefore, a beam collimation system is essential not only for control of experimental backgrounds but also for safely disposing of unavoidable beam losses and ensuring machine availability. Unique challenges for the collimation system design need to be addressed, and the exploitation of channeling of charged particles in a bent-crystal-assisted collimation scheme is being explored as a possible solution to improve collimation performance. This paper presents the first studies to assess the feasibility of implementing such a collimation scheme in the FCC-ee.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
