Multimodales luftgestütztes Quantensenorinstrument für die nachhaltige Exploration (MAQSIMAL)

---

To secure today a sustainable supply with critical (and strategic) raw materials (CRM and SRM), advanced, non-invasive, environmentally friendly methods are required which are able to: search for new resources at ever greater depths of > 500m, be applicable to new characters of mineral resources tobe discovered such as smaller in size and/or very deeply buried, located in hazardous areas (e.g. subarctic or desert conditions etc.), discover disseminated ore, be ecologically less demanding and be accepted by the public. These preconditions demand new tailored instruments and sensors with high bandwidth and ultra-high resolution. In this context, QUANTUM SENSORS for the detection of faint magnetic field changes, so-called quantum magnetometers, have the potential of revolutionizing our measurement capabilities and instrumentation and thus impact also the correspondent exploration methods in geophysics. In Multimodal Airborne Quantum Sensor lnstruMent for sustAinable expLoration (MAQSIMAL) the consortium envisions a unique and miniaturized demonstrator instrument based only on hybrid read out Superconducting Quantum lnterference Devices which is able to simultaneously record multiple measurement modalities such as the magnetic field vector, the full tensor magnetic gradient, audio-frequency magnetics (AFMAG), and audio-magnetotelluric data at utmost precision , high bandwidth, and unprecedented dynamic range (>32 bit) using a modular data acquisition system installed on an advanced helicopter-towed platform in airborne and semi-airborne methods. The demonstrator will be complemented with according software tools for (1) post-mission data processing implementing synchronisation, GPS and base station data, inertial data, de-jumping, calibration and compensation and (2) inversion of individual modalities or joint inversions using all or a subset of modalities. The performance will be evaluated over two representative targets for CRM/SRM resources in Sweden and in Portugal.
