In 1997, the Institute for Physical High-Technology (IPHT) in Jena, Germany, started a program with the aim of developing an airborne full-tensor magnetic gradiometer superconducting quantum interference device (SQUID) using liquid-helium-based thin-film technology. Since that time, the sensor, system electronics, data acquisition system, and cryogenics have been developed and extensively tested. This article reports on successful tests of the intrinsic planar LTS (low-temperature superconductor) SQUID gradiometers which were conducted by towing the system from a helicopter as well as for a stinger-mounted configuration in a Cessna 208 aircraft.
