| Popis: | After successful tests with the GSI-CCC prototype, measuring beam intensities down to 2nA at a bandwidth of 10 kHz, a new advanced Cryogenic Current Comparator system with extended geometry (CCC-XD) is under development. This system will be installed in the upcoming Cryring facility for further optimization, beam diagnostics and as an additional instrument for physics experiments. After the test phase in Cryring it is foreseen to build four additional CCC units for FAIR, where they will be installed in the HEBT lines and in the Collector Ring (CR). A universal cryostat has been designed to cope with the various boundary conditions at FAIR and at the same time to allow for uncomplicated access to the inner components. To realize this compact cryostat, the size of the superconducting magnetic shielding has to be minimized as well, without affecting its field attenuation properties. Hence detailed FEM simulations were performed to optimize the attenuation factor by variation of geometrical parameters of the shield. The beam tests results with the GSI-CCC prototype, and the developments for FAIR, as well as the results of simulation for magnetic shield optimization will be presented. Proceedings of the 5th Int.
