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

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 ±6 μm, 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.
