Abstract
Interactions between ions and non-homogeneously distributed electrons in a min-B plasma trap result in an anisotropic ion distribution. Since phenomena like Kα X-ray emission and β-decay depend on the ion properties, knowledge of the ion spatial distribution is vital to correlate it with the experimental counterparts of said processes. We present a numerical study connecting electron dynamics with anisotropic ion distribution, based on space-selective ion CSD calculation using a population kinetics code. This was first developed to supplement experimental Xray imaging plasma diagnostics, but it can now be extended to obtain insights on β-decay rates for the PANDORA Gr3 (Plasmas for Astrophysics, Nuclear Decay Observations and Radiation for Archaeometry) project as well.| File | Dimensione | Formato | |
