Given by the wide beam energy and intensity ranges planned in the FAIR beam lines, seven CCC systems are foreseen to be installed at its transfer lines and storage rings. Hence in 2009, this project was re-started to develop improved CCC systems by incorporating advanced components and instrumentations.

After successful re-commission of the existing GS-CCC system and a number of optimization measurements, this CCC system was used as a test bench for measurements for with the new sensor and data acquisition units. The dc SQUID sensor and the associated electronics developed at FSU, Jena was replaced by commercial alternatives based on modern technology. The system was then installed at the extraction section of SIS18 and successful beam measurements were done during spring 2014 beam time followed by extensive offline tests. Apart from the already known zero drift, the offline tests revealed strong instantaneous dependence of temperature/pressure of the liquid helium cryostat on the CCC output. These investigations are still under progress to confirm the origin of these influences and to minimize them in the future systems.
