Abstract
An NMR DNP-MAS probe head () has an MAS stator () for receiving an MAS rotor () having a sample substance in a sample volume (), and a hollow microwave waveguide ()' for feeding microwave radiation through an opening () of the microwave waveguide into the sample volume, an axially expanded rod-shaped microwave coupler () located in the opening made of dielectric material, characterized in that the microwave waveguide has a conically tapered hollow transition piece for coupling in an HE 11 mode, into which the microwave coupler projects at an all-round radial distance to the opening of the microwave waveguide. It is thus possible, in a surprisingly simple manner and by means of readily available technical means, to irradiate a considerably higher microwave energy in the HE 11 mode into the NMR measuring sample than by means of the known arrangements.
