Sensitivity and noise analysis of solenoidal coils for nuclear magnetic resonance microscopy

Conventional NMR studies involve sample volumes $(\upsilon\sb{s})$ of several cubic millimeters and greater. Much recent interest is directed at the development of microscopic NMR systems for the analysis of smaller samples and the visualization of microscopic biological structures. The objective of the research summarized in this thesis is to extend the analysis of RF coils used for NMR to microscopic domains. Microscopic nuclear magnetic resonance suffers from an inherently low SNR, due to the small number of nuclei available to contribute to the signal. Decreasing the size of the RF receive coil provides better coupling between the sample being examined and the coil, i.e., it increases the sensitivity of the coil. We define the sensitivity of a coil as the magnitude of the RF magnetic field that is produced in the coil when a unit current is passed through the windings of the coil.
