Abstract
E021 DEVELOPMENT OF A NEW MAGNETO- ELECTRICAL RESISTIVITY IMAGING SYSTEM A. Verweerd 1 2 E. Zimmermann 1 A. Tillmann 2 W. Glaas 1 A. Kemna 2 1 A new Magneto Electrical Resistivity Imaging System is proposed which combines measurement of the electric potential and the magnetic field due to a current injection into a probe. For the magnetic field measurements 24 new sensor modules were developed mounted on a vertically moving scanning torus. The system is designed to operate in a typical laboratory magnetic noise environment without extensive shielding and for cylindrical samples. Optimal noise reduction is provided by the
