Summary on Grant Application Form |
|
Relaxation Oscillation SQUIDs, (ROSs) are a significant advance over conventional dc SQUIDs. Single ROSs generate voltage pulses whose frequency varies with the flux in the SQUID loop and are therefore ideal for digital readout. Double ROSs (D-ROSs) have a much larger flux to voltage transfer function than conventional SQUIDs. This permits direct analogue readout without the need for flux modulation (which limits the bandwidth) or bulky cooled matching circuits. In this project we aim to develop the first ROS sensors based on High Temperature Superconductors and explore their applications. HTS ROSs will permit the development of HTS digital SQUIDs via novel and elegant routes which minimise the number of junctions required. HTS D-ROSs will have enhanced bandwidth and significantly simpler readout electronics than that of other types of HTS SQUID and this will widen the range of applications for HTS sensors. The project will also involve investigation of integrated resistors for HTS circuits. This collaboration brings to bear the expertise of Strathclyde University in the SQUID area and that of the IRC in Superconductivity in HTS thin films and devices upon the development a novel class of high performance magnetic sensor.
