Methods for the analysis and design of a solid state nuclear magnetic resonance probe

Methods for the analysis and design of solid state nuclear magnetic resonance (NMR) probes are presented. These techniques have been applied to a 200 MHz (H-1 Larmor frequency) H-1-F-19-C-13 cross polarization magic angle spinning probe. Transmission lines have been used throughout the design enabling the production of a highly power efficient probe (H-1-22%, F-19-17%, and C-13-33%) capable of detecting F-19 NMR signals while applying proton decoupling fields of 250 kHz. These techniques have proven very useful in designing the probe discussed within the text but are not confined to such a triple resonant design. In fact the techniques are sufficiently general to be useful to all radio frequency design efforts including deuterium wide-line probes and multiresonant high resolution NMR probes. A series of simple but useful design concepts are presented which are used to predict the efficiencies of the design presented. (C) 1998 American Institute of Physics. [S0034-6748(98)01309-4]
