Abstract
Following the positive outcomes and successful application of Low Temperature SQUIDs (LTS) as ground TEM B-field sensors, a research and development program was launched to try and realize similar benefits in airborne EM applications. The AeroTEM III helicopter-slung bird had been selected as the prototype platform for the integration of the IPHT / Supracon LTS EM SQUID sensor technology with a new generation experimental airborne EM system. A number of ground-based and two airborne flight tests were conducted, first in December 2007 with a 100% duty cycle Spectrem (“on-time”) waveform and then in September 2008 with an AeroTEM triangular “off-time” waveform.
