SRF PIP-II 串组件的对准被研究为可接受的光束偏转、偏移和散焦，否则可能会导致光束损失。模拟和测量表明，束管与参考轨道的最大偏差不应超过束孔径的一小部分。为了观察低温模块内每个组件的平移和旋转，使用了安装在模块内部组件中的光学仪器 (H-BCAM) 来测量高反射目标。本贡献介绍了 PIP II SSR1 原型低温模块的对准监控概念，以及冷体冷却期间组件位置监控的相关测量。这一发展为洁净室环境中低温模块组件领域的新计算机视觉应用铺平了道路，其中机器人辅助操作有可能显着降低化学和颗粒污染的风险。
The alignment of the SRF PIP-II string components is studied as the acceptable beam deflection, offset and defo-cusing, which may otherwise cause beam loss. Simulations and measurements established that the maximum deviation of the beam pipe from the reference orbit should not exceed a small fraction of the beam aperture. To observe the translations and rotations of each single component within the cryomodule, optical instruments (H-BCAM) surveying highly reflective targets, installed in the internal assembly of the module were used. The alignment monitoring concept for the PIP II SSR1 prototype cryomodule, along with relevant measurements of the components’ position monitoring during coldmass cooldown is presented in this contribution. This development paves the way to new computer vision applications in the field of cryomodule assemblies in clean-room environment, in which robotically-assisted operations have the potential to dramatically reduce the risk of chemical and particulate contamination.
