The principles of the superconducting cryogenic direct-current comparator (CCC) is applied to the non-invasive sensing of charged-particle beams (ions, electrons). With the use of HTS components it is feasible to envisage applications, for example, in precision mass spectrometry, in real-time monitoring of ion-beam implantation currents and for the determination of the Faraday fundamental constant. We have developed a novel current concentrating technique using HTS thick film material, to increase the sensitivity of the CCC. Recent simulations and experimental measurements of the flux can current concentration ratios, frequency response and linearity of a prototype HTS-CCC operating at 77k are described.
