Augmenting microwave irradiation in MAS DNP NMR samples at 263 GHz

Purea, A.; Ell, B.; Reiter, C.; Aussenac, F.; Engelke, F.

Abstract:
The magnetic microwave field strength and its detailed spatial distribution in magic-angle spinning (MAS) nuclear magnetic resonance (NMR) probes capable of dynamic nuclear polarization (DNP) is investigated by numerical simulations with the objective to augment the magnetic microwave amplitude by structuring the sample in the mm and sub-mm range and by improving the coupling of the incident microwave beam to the sample. As it will be shown experimentally, both measures lead to an increase of the microwave efficiency in DNP MAS NMR.
