| Sumario: | A vibrating wire is used to measure the longitudinal profile of the magnetic flux density in
the aperture of a non-periodical structure such as a quadrupole accelerator magnet. Limitations in terms of measurement repeatability and uncertainty are observed.
The possible causes are investigated by experimental characterization of the measurement system. Uncertainty sources are identified and particular cases are reported in which the mathematical assumptions are no longer valid. The challenges are discussed and measures are proposed to improve the metrological performance. |
