AI Technical Summary

Technical Problem

Existing technologies have limitations in single-dimensional error monitoring and reliability defects in active compensation systems during the positioning and installation of ultra-long devices for large particle beam experiments. They cannot effectively monitor and adjust cumulative errors, especially those caused by thermal deformation, settlement, and vibration, leading to unstable equipment operation.

Method used

Employing a multi-technology fusion real-time measurement technology and a passive error compensation scheme, the system monitors six-degree-of-freedom pose deviations in real time through a multi-sensor network and achieves error self-cancellation by combining the intrinsic properties of materials. This includes segmented installation of beam optical magnet units, deployment of multi-sensor networks, real-time data synchronization, error threshold judgment, and automatic compensation correction.

Benefits of technology

It achieves precise monitoring and compensation for cumulative errors from μm to mm, ensuring the stability and accuracy of the device. It covers multiple error sources, including geometric installation deviations, thermal deformation, foundation settlement and vibration, providing core protection.

Abstract

A technique for eliminating cumulative errors in the positioning and installation of a large-scale particle beam experimental ultra-long device is disclosed, comprising: 1) segmented installation of the beam optical magnet unit, including positioning magnets along the axis of the ultra-long device at designed intervals, pre-tightening them to a specified torque using high-strength bolts, and coarsely adjusting the initial pose to within ±100μm using a total station; 2) deployment of a multi-sensor network; 3) real-time synchronous data acquisition based on the multi-sensor network in step 2), with all data synchronized within 1ms via the PTP protocol; 4) reconstruction of the magnet constraint deformation field; 5) judgment of the cumulative error threshold; 6) automatic compensation and correction by a supplementary system, including self-compensation for thermal deformation, settlement and angle correction, and vibration energy dissipation; and 7) closed-loop accuracy verification to complete the installation.
