%X A new Cryogenic Current Comparator with eXtendedDimensions (CCC-XD), compared to earlier versions builtfor GSI, is currently under development for a non-destructive,highly-sensitive monitoring of nA-intensities ofbeams for larger beamline diameters planned for the newFAIR accelerator facility at GSI. The CCC consists of a:1) flux concentrator,2) superconducting shield against external magneticfield and a3) superconducting toroidal coil of niobium which isread out by a4) Superconducting Quantum Interference Device(SQUID).The new flux concentrator (1) comprises a specially designedhighly-permeable core made of nano-crystallinematerial, in order to assure low-noise operation with highsystem bandwidth of up to 200 kHz. The superconductingshielding of niobium (2) is extended in its geometric dimensionscompared to the predecessor CCC and thus willsuppress (better -200 dB) disturbing magnetic fields of thebeamline environment more effectively. For the CCD-XDreadout, new SQUID sensors (4) with sub-μm Josephsonjunctions are used which enable the lowest possible noiselimitedcurrent resolution in combination with a good suppressionof external disturbances.The CCC-XD system, together with a new dedicated cryostat,will be ready for testing in the CRYRING at GSI inspring 2017. For the application of a CCC in the antiprotonstorage ring at CERN a pulse shape correction has been developedand tested in parallel. Results from electricalmeasurements of two components (1 and 4) of the newCCC-XD setup will be presented in this work.
