SIRIUS-B: Simple and rapid imaging of groundwater using magnetic resonance using grounded bipoles

The project targets at using electrical bipoles for NMR excitation and signal detection as alternative to heavy-weight instruments with large loop layouts

Project objectives

Unlike the loops that transmit and detect the magnetic field component of the electromagnetic field, the grounded electrodes transmit and detect the electrical field component. The difference sounds simple but the approach has not been considered, yet. Since the invention of magnetic resonance, large surface loops have been used. However, in other geophysical electromagnetic methods measurements of the electrical field component are commonly considered.

SIRIUS B will investigate using grounded bipoles both for transmitting NMR pulses and receiving NMR signals.
