Metrological characterization of field markers for real-time measurement and control of accelerator magnets

In the framework of magnetic measurements in particle accelerator application, the problem of the drift due to the integration of a voltage offset causes a lack of stability which is inadequate for long-term measurements. In this thesis, a new approach for the modelling and correction of long-term drift in integrators is discussed. The technique consists of a novel feed-forward drift correction method combined with the use of a field marker and tested by using experimental data retrieved from the existing B-train systems from ELENA and PSB.
