| This joined project was successfully shown to measure ion beam current down to <10 nA with a bandwidth exceeding 10 kHz. The non-intercepting and absolute measurement possibilities with a wide dynamic range using CCC provided interesting applications in beam diagnostics. Intensity measurements independent of beam energy, type and trajectories with absolute calibration provided the possibility of calibration of other standard intensity measurement devices, especially in the low intensity ranges, where standard beam current transformers cannot be used.\\ | This joined project was successfully shown to measure ion beam current down to <10 nA with a bandwidth exceeding 10 kHz.
