Bio-DNP Design Study
Shuttle DNP Spectrometer (DS3)
A complete shuttle DNP NMR spectrometer has been built and its principal operation has been proven. First Overhauser-DNP experiments were performed with polarization transfer in low field, shuttling, and NMR detection in high field. The hardware setup will be now subject to successive improvements in order to enhance the DNP NMR signal further, to make the system more stable and to extend the system to better control the relaxation of the sample during shuttling.
Shuttle Spectrometer: overview of shuttle DNP spectrometer. A 600 MHz NMR
spectrometer with a X-Band EPR spectrometer on top. An air driven sample shuttle
moves the sample within a few milliseconds from the EPR to the NMR cavity, and
vice versa.

600MHz NMR magnet)
