These non-destructive charged particle beam monitoring systems are able to measure intensities in the nA-range with a white noise level below 5 pA/sqrt(Hz). The systems are sensitive from DC to several hundred kHz and can be linked-up in a traceable way with national and international ampere-standards. In its present design, the base body consists of a highly-permeable, nano-crystalline core optimized for low-temperatures (ready for superfluid He-II applications) and a niobium shielding/pickup-coil unit. The flexible SQUID (Superconducting Quantum Interference Device) - cartridge allows for application tuning. Three cartridge versions (direct, balanced and enhanced) will be presented, discussed and results of electrical laboratory measurements of the noise behaviour and the frequency response will be given.
