Abstract

A cylindrical cavity working in TM110 mode at the X-band frequencies was designed and manufactured for dynamic nuclear polarization (DNP) systems. The dimensions of the cavity were theoretically calculated, and then optimized with the software Ansoft-HFSS. The fabricated probe was tested experimentally on a homebuilt DNP system. With the probe,1H NMR signal was acquired with more than 50-folds of sensitivity enhancement; and a clear DNP-enhanced image was obtained.

Key words： probe; dynamic nuclear polarization (DNP); MRI; TM110; cavity
