Instrumentation for Local and Integral Field Measurements of Superconducting Undulator Coils

摘要

Accurate magnetic field measurements are a prerequisite for the characterization and optimization of undulators. The precision for measuring the magnetic properties of conventional, i.e., permanent magnet based insertion devices, has undergone tremendous improvements over the past 10 to 15 years initiating a new era in synchrotron light sources worldwide; a similar breakthrough is now necessary in the field of superconducting insertion devices.
