Simulating steady-state sequences in surface NMR

PhD defence, Monday 16 January 2023, Matthew Peter Griffiths

Matthew Peter Griffiths

Surface nuclear magnetic resonance (NMR) is the only geophysical method that is directly sensitive to groundwater, using surface-based transmitter and receiver coils. Recently developed surface NMR instruments can transmit novel pulse-train excitations (steady-state excitations), that can yield high quality data in a fraction of the time. However, the current modelling schemes are not capable of simulating these measurements, due to practical limitations stemming from the computational load. During his PhD studies, Matthew developed approaches to simulating these measurements to make use of this exciting new style of data.


The PhD study was completed at , Faculty of Technical Sciences, Aarhus University.
