Summary
Magnetic High temperature Sensors (MagHITS) aims for the novel development and demonstration of ultra-high-temperature vector magnetometers.
The main challenge for magnetometry at very high temperatures is sensor material degradation that causes the magnetic sensors to drift or become non-operational. Potentially groundbreaking, ultra-high-temperature vector magnetometers would enable improved oil and gas exploration and improved stability in magnetic confinement for nuclear fusion reactors.
The MagHITS program is an 18-month Microsystems Exploration effort with two phases.
- Phase 1 will focus on the feasibility, from theoretical and implementation points of view, of producing a high-temperature (to 500 °C/932°F) vector magnetometer.
- Phase 2 will develop proofs of concept of the high-temperature vector magnetometer prototype through lab bench demonstrations.
The program will produce magnetic sensor proof-of-concept demonstrations, with probe elements that operate at temperatures up to 500 °C/932°F, with a sensitivity of 100 pT/√Hz in the frequency range of 0.1-100 Hz.
