Abstract :
The principle of the superconducting cryogenic direct-current comparator (CCC) is applied to the non-invasive sensing of charged-particle beams (ions, electrons). 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 a prototype HTS-CCC operating at 77 K are described.
