Spin dynamics and ortho-para conversion in HO during the phase transition from gas to solid in external magnetic fields
Chrysovalantis S. Kannis, Ralf Engels, Nicolas Faatz +2
The spin dynamics of water ice in the presence of external magnetic fields are investigated. The employed model is based on the approach introduced by Buntkowsky et al. [Z. Phys. C…
Production of Spin-Polarized Molecular Beams via Microwave or Infrared Rotational Excitation
C. S. Kannis, T. P. Rakitzis
We propose schemes to produce highly nuclear-spin polarized small molecules in an intense and cold molecular beam via microwave or infrared rotational excitation, followed by hyper…
Spin manipulation and nuclear polarization enhancement in particle beams with static magnetic fields
Chrysovalantis S. Kannis, Ralf Engels, Tarek El-Kordy +5
A theoretical study of spin dynamics in non-relativistic particle beams with interacting angular momenta traversing static, spatially varying magnetic fields is presented. The comp…
STORI2024: Tests of Amorphous Carbon-coated Storage Cells for a Polarized Gas Target at LHCb and Further Results
Tarek El-Kordy, Ralf Engels, Nicolas Faatz +7
As the LHC beams cannot be polarized, introducing a dense polarized gas target at the LHCb experiment at CERN, to be operated concurrently with beam-beam collisions, will facilitat…
Preservation of He ion polarization after laser-plasma acceleration
Chuan Zheng, Pavel Fedorets, Ralf Engels +11
The preservation of nuclear spin alignment in plasmas is a prerequisite for important applications, such as energy production through polarized fusion or the acceleration of polari…
