摘要

紧凑型直线对撞机（CLIC）主直线对撞机采用波导阻尼结构作为基准设计。为了保证光束的动态稳定性，在0.5 ns内横向尾流场必须小于3.4 V/pC/m/mm，与第二束的位置相对应。本研究的重点是通过新材料测量优化高阶模态（HOM）阻尼载荷，实现对远程横向尾流场的增强抑制。新的阻尼载荷比以前的CLIC结构设计紧凑20%。

HOM SiC loads for CLIC X-band structures: Design and measurements

The Compact Linear Collider (CLIC) main linac employs a waveguide-damped structure as its baseline design. To ensure beam dynamic stability, the transverse wakefield must be less than 3.4 V/pC/m/mm in 0.5 ns, corresponding with the position of the second bunch. This study focuses on optimizing high-order-mode (HOM) damping loads through new material measurements, achieving enhanced suppression of long-range transverse wakefields. The new damping load is 20% more compact than those in the previous CLIC structure design.

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.
