Abstract (english)
Assurance of high measuring sensitivity is one of the most challenging issues of any nuclear magnetic resonance (NMR) spectroscopy system. To this end, we propose an accurate noise model of the entire probe-to- spectrometer receiving chain for condensed matter physics, based on a concept of noise figure. The model predicts propagation of both signal and noise level at every component of the NMR spectroscopy receiving chain. Furthermore, it enables identification of the "weakest" component and, therefore, the optimization of the whole system. The most important property of the proposed model is the possibility to find system parameters that reduce measurement time by an a priori calculation, rather than an a posteriori approach. The model was tested experimentally on several different samples. It was found that the measurement time can still be significantly shortened, down to at least one half of the measurement time, starting from optimized conditions with commercially available components. Thus, the proposed model can be used as a tool for both quantitative analysis of the noise properties and sensitivity prediction of practical NMR systems in physics and material science.
