In previous work we looked in detail at simulations of our HTS Resistive DC SQUIDs (RSQUIDs) using a lumped-component model and neglecting step-edge junction capacitance. These can now be made with junctions that have a high product of critical curre

The ability to reduce SQUID dimensions into the sub-micrometer or nanometer regime points the way towards novel applications, particularly in emerging fields such as quantum information processing, single-photon/particle detection, and experimental s

We report the development of a novel form of bolometric detector, which may have widespread application to particle detection and energy resolved measurement, and may be applicable to massive particles, photons or even phonons. The basis for bolometr
