Modern high-field DNP NMR spectrometers are typically based on a cryogenic magic-angle sample spinning (MAS) capability.
January 17, 2018 - This article is not specifically about DNP spectroscopy. However, magic angle spinning at 6K is definitely of interest to DNP, especially when using low-power, solid-state microwave sources.
December 6, 2017 - This article has nothing to do with DNP. However, the article nicely describes an impressive piece of isntrumentation to reach very low temperatures.
