Abstract

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 break through is now necessary in the field of superconducting insertion devices. In this contribution we describe the planned instrumentation needed to perform magnetic measurements of the local field, and field integrals, of up to 2 m length superconducting undulator coils while in a cold-in-vacuum (helium free) environment.
