 ===== N-DCCT (Novel DC Current Transformer) =====
-The N-DCCT is a DC beam current transformer, based on GMR magnetic sensor technology. It is designated to measure the high intensity beam currents circulating in the FAIR synchrotron SIS100. R&D were enforced by a collaboration with the University of Kassel/Dept. for Electrical Engineering/Measurement Instrumentation Group (now concluded).

-Motivation: The well-known "magnetic-modulator" or "flux gate" principle up to now used in the designs of DCCTs shows disturbed performance at highest beam currents, due to interactions between signal and modulation frquencies, electronic slew rate limitations, common-mode EMI, etc.
