Cryopumping of Hydrogen Amd Helium*
Cryopumping is of interest to both fusion reactors and particle accelerators since it can provide the following features: (1) very high pumping speed ever a large pressure range; (2) very low equilibrium pressure; (3) very large capacity; (4) cleanliness; (3) ability to store ehe pumped species on the cryosurface for later recovery; (6) neither high voltage nor magnetic field is required, which...
متن کاملCollision kernels from velocity-selective optical pumping with magnetic depolarization
We experimentally demonstrate how magnetic depolarization of velocity-selective optical pumping can be used to single out the collisional cusp kernel best describing spinand velocity-relaxing collisions between potassium atoms and low-pressure helium. The range of pressures and transverse fields used simulate the optical pumping regime pertinent to sodium guidestars employed in adaptive optics....
متن کاملMagnetic Field Effects on the 1083 nm Atomic Line of Helium Optical Pumping of Helium and Optical Polarisation Measurement in High Magnetic Field
The structure of the excited 2S and 2P triplet states of He and He in an applied magnetic field B is studied using different approximations of the atomic Hamiltonian. All optical transitions (line positions and intensities) of the 1083 nm 2S-2P transition are computed as a function of B. The effect of metastability exchange collisions between atoms in the ground state and in the 2S metastable s...
متن کاملAdvances in optically pumped He4 magnetometers : Resonance and nonresonance techniques
2014 Samples of optically pumped 23S1 helium atoms are currently studied in our laboratory for use in advanced magnetometer applications. The results of recent investigations of the effect of pumping beam orientation with respect to the observed magnetic field are presented in this paper. The orientation dependence of the amplitude and frequency of the magnetic resonance signal observed by opti...
متن کاملHe in situ
Polarized helium-3 is used as a contrast agent for lungs magnetic resonance imaging that has recently reached the pre-clinical applications. One method to hyperpolarize He is the metastability exchange optical pumping (MEOP). Optical pumping is performed in standard conditions at low pressure ( 1 mbar) and low magnetic field ( 1 Gauss). In this work, the complete update of a low field polarizer...
