Fast Sample Shuttling for experiencing and correlating multiple magnetic fields

This direction of research was initiated with the DYN-IDP project in collaboration with the UMR 7203 of the Ecole Normale Superieure (Dr. Fabien Ferrage), and was funded by the ANR. A fruitfull collaboration with Prof. Tai-huang Huang from Academia Sinica allowed us to acquire and adapt a ultra-fast mechanical sample-shuttling device on our narrowbore (700 MHz) and widebore (500 MHz) high field NMR spectrometers.
Pioneering work in the field of high-resolution relaxometry using sample shuttling has been performed by A. Redfield. Our recent collaboration with the ENS has produced a recent result using a pneumatic sample shuttling from Bruker that can be found: here and here. The collaboration with Academia Sinica has allowed us to demonstrate that the ultra-fast mechanical shuttling device can be used on a standard 700 MHz system with a 5 mm cryoprobe and allow the acquisition of high-resolution protein relaxometry at standard concentrations.
One research direction is to mount a fast sample shuttling device on various high-field superconducting magnets and use it to measure the relaxation properties of matter in high-sensitivity and high-resolution conditions. Permanent magnet inserts can be used to generate secondary homogeneous spots inside or outside of the bore of the superconducting magnet. This possibility will allow for correlation experiments between the mutliple centers, with high sensitivity and resolution. The concept is summarized on the next figure.
