“cryogen-free” magnet that can generate fields up to 9.4 T with a sample space that can
reach temperatures below 1.4 K in a continuous and stable manner. Polarization levels up to
P (1 H)= 60±5% can be reached with TEMPOL in about 20 min, and P (13 C)= 50±5% can
be achieved using adiabatic cross polarization.
