Abstract: A Cryogenic Current Comparator (CCC) wasdeveloped for the upcoming FAIR-Project, providing anon-destructive online monitoring of the beam current inthe nA-range. The CCC was optimized for a lowestpossible noise-limited current resolution together with ahigh system bandwidth. Therefore, the low temperatureproperties of ferromagnetic core materials used in thepick-up coil were investigated and differentSuperconducting Quantum Interference Device (SQUID)-systems were tested.In this contribution we present results of the completedCryogenic Current Comparator for FAIR working in alaboratory environment, regarding the improvements inresolution and bandwidth due to the use of suitableferromagnetic core materials and optimized SQUIDsystemcomponents.
