NUCLEAR

The NPG also operates a cryogenically cooled solid polarized target lab in support of the Tensor Spin Observables program. The system operates at 1 Kelvin and 5-7 Tesla using a mm-wave solid state source to stimulate Dynamic Nuclear Polarization (DNP) of deuterated samples. We recently installed a new helium reliquifier system from Quantum Technologies to support the DNP system. We also operate a material preparation lab where we chemically introduce the paramagnetic impurities necessary for the DNP process, or alternately introduce these centers via irradiation at the NIST MIRF accelerator.
