Table 1 Summary of performance data using an inductively coupled Lenz lens resonator.

The average pressure, p, was obtained at the center of the 250-μm culeted diamond anvil. The 90° pulse lengths, tπ/2, were obtained by nutation experiments at 1-W pulse power and used to estimate the average RF magnetic field strengths 〈B1〉. LODt was estimated given the obtained time-domain SNR, SNRt, a number of about Embedded Image hydrogen nuclei in the sample cavity, and a receiver bandwidth of 2 MHz at all measurements.
