摘要:

自1989年以来,IHEP Protvino率先将弯曲晶体作为高能束中的光学元件,用于永久性的光束提取和偏转。在IHEP实验的过程中,晶体沟道已经发展成为加速器中粒子转向的有效工具,多年来以可预测的、可靠的方式与非常高强度的光束一起工作。基于理论上提出并在IHEP实验上实现的沟道多程机制,晶体系统在1.E12强度下从IHEP主环中提取了70 GeV的质子,效率为85%。今天,IHEP 70-GeV加速器设施主环上的六个位置配备了晶体提取系统,主要用于常规应用而不是研究,并允许同时运行多个粒子物理实验,从而大大丰富了IHEP物理计划。IHEP大规模晶体开发的长期成功历史应有助于将沟道晶体纳入全球加速器系统,以创建独特的束流传输系统。我们报告了IHEP晶体萃取系统的研究和开发的最新结果。

英文摘要:

IHEP Protvino has pioneered the wide practical use of bent crystals as optical elements in high-energy beams for beam extraction and deflection on permanent basis since 1989. In the course of IHEP experiments, crystal channeling has been developed into efficient instrument for particle steering at accelerators, working in predictable, reliable manner with beams of very high intensity over years. Crystal systems extract 70 GeV protons from IHEP main ring with efficiency of 85% at intensity of 1.E12, basing on multi-pass mechanism of channeling proposed theoretically and realised experimentally at IHEP. Today, six locations on the IHEP 70-GeV main ring of the accelerator facility are equipped by crystal extraction systems, serving mostly for routine applications rather than for research and allowing a simultaneous run of several particle physics experiments, thus significantly enriching the IHEP physics program. The long successful history of large-scale crystal exploitation at IHEP should help to incorporate channeling crystals into accelerator systems worldwide in order to create unique systems for beam delivery. We report recent results from the research and exploitation of crystal extraction systems at IHEP.
