Abstract:

Clandestine mine reconnaissance is the Navys highest MCM priority. During the 1980s, the Superconducting GradiometerMagnetometer Sensor SGMS was demonstrated in the Magnetic and Acoustic Detection of Mines MADOM ATD to provide effective detectionclassification capabilities, especially against buried mines, and to reduce significantly acoustic false alarms arising from bottom clutter 1, 2. This sensor utilized the low critical temperature low Tc superconductor niobium and required liquid helium for sensor cooling. Advanced magnetic sensor approaches are being developed to transition this technology to the fleet. The current focus of this project is to develop an advanced High Tc Superconducting Gradiometer HTSG prototype cooled by liquid nitrogen in order to attain long detection ranges in substantially reduced package sizes with minimal cryogen support requirements and to demonstrate it at sea in FY 1999.
