Platform Construction of Single Stretched Wire Method and Related Experimental Test Research

张力线法作为一种优质的磁场测量方法,具有定位精度高、测量快捷、可测量小孔径磁体等优势,被许多国外实验室所采用并广泛应用于加速器磁场测量领域当中。本工作研究了张力线测量方法的相关理论,搭建了一套张力线磁场测量平台;并对一台常规四极铁进行了一系列的测试实验,研究了信号处理方法并验证了测量精度。结果表明,该张力线系统的磁中心测量重复性精度好于±6μm,满足大部分加速器工程的测试需求。未来该系统还将继续完善并广泛应用于相关装置的磁场测量工作中。

The SSW(Single Stretched Wire)method is a high-quality magnetic field measurement technique that offers benefits like excellent positioning precision,quick measurement and tiny aperture magnets measurement.It is widely employed in the field of accelerator engineering magnetic field measurement and has been adopted by numerous overseas institutions.In this study,a set of SSW magnetic field measurement platforms are constructed based on the theory of the SSW measurement method,and a number of tests are run on a standard quadrupole to examine the signal processing technique and confirm the measurement accuracy.The findings demonstrate that the SSW system's magnetic center measurement repeatability is better than±6μm,which satisfies the test requirements for the majority of accelerator projects.In the future,this system will continue to be improved and widely used in the magnetic field measurement of related devices.
