It measures the intensity of lowest beam currents, circulating in storage rings, or extracted through high energy beam transport lines. The present best values, obtained with a thin-film DC SQUID at 4.2 K, are: |
* Current resolution < 6-120 pA/sqrt(Hz) (within a bandwidth of DC-10 kHz) | * Current resolution < 6-120 pA/sqrt(Hz) (within a bandwidth of DC-10 kHz) | ||

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.\\ | 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.
