With a recent announcement of a persistent 21.15 Tesla (i.e., 900 MHz for 1H NMR) narrow-bore (54 mm bore) superconducting magnet by Oxford instruments and the associated Unity INOVA-900 console by Varian Inc. We were challenged with the task of designing a double resonance broadband solid-state magnetic magic-angle spinning (MAS) NMR probe. In particular for evaluating the 13C-(1H) cross-polarization (CP) MAS NMR experiment on this magnet and spectrometer system. In this communication we report the successful construction of an efficient X-1H/19F double resonance multinuclear MAS probe for this purpose along with our preliminary results on its performance at the 900 MHz spectrometer.
