Nuclear hyperpolarization of 3He by magnetized plasmas
A. Maul, P. Blümler, P. -J. Nacher +3
We describe a method to hyperpolarize 3He nuclear spins at high magnetic fields (4.7 Tesla) solely by a magnetized plasma. The conditions for such a magnetized plasma are fulfilled…
Metastability Exchange Optical Pumping of Helium-3 at High Pressures and 1.5 T: Comparison of two Optical Pumping Transitions
Marie Abboud, Alice Sinatra, Geneviève Tastevin +2
At low magnetic field, metastability exchange optical pumping of helium-3 is known to provide high nuclear polarizations for pressures around 1 mbar. In a recent paper, we demonstr…
A broadband Ytterbium-doped tunable fiber laser for 3He optical pumping at 1083 nm
Genevieve Tastevin, Sebastien Grot, Emmanuel Courtade +2
Large amounts of hyperpolarized 3He gas with high nuclear polarization rates are required for use in neutron spin filters or nuclear magnetic resonance imaging of human lung. Very…
High nuclear polarization of helium-3 at low and high pressure by metastability exchange optical pumping at 1.5 Tesla
Marie Abboud, Alice Sinatra, Xavier Maitre +2
We perform metastability exchange optical pumping of helium-3 in a strong magnetic field of 1.5 T. The achieved nuclear polarization, from 80% at 1.33 mbar to 25% at 67 mbar, shows…
Magnetic Field Effects on the 1083 nm Atomic Line of Helium. Optical Pumping of Helium and Optical Polarisation Measurement in High Magnetic Field
E. Courtade, F. Marion, P. -J. Nacher +3
The structure of the excited S and P triplet states of He and He in an applied magnetic field B is studied using different approximations of the atomic Ha…
