We planned to improve the polarization to 50%, which is a sufficiently practical level, by increasing the magnetic field to 6.3 T and improving the sample cooling efficiency. The sample cooling efficiency can be improved by the insert design by circulating cryogenic helium gas from the bottom of the sample cell through the top side of the insert, the temperature rise due to microwave application will be reduced.
