Integrated analysis and consistency measurement of bremsstrahlung and charge exchange spectroscopy data for the determination of the ion effective charge.
In the context of Bayesian probability theory, we discuss a model for estimating the plasma ion effective charge Z(eff), integrating data from both bremsstrahlung spectroscopy and individual impurity concentrations obtained via charge exchange spectroscopy (CXS). The validity of the model, taking into account statistical as well as systematic uncertainties, is shown via the deviance information...
متن کاملIon Condensation in the Electric Double Layer and the Corresponding Poisson-Boltzmann Effective Surface Charge
The effective surface charge obtained by fitting the Poisson-Boltzmann approximation to measured data is related to the actual surface charge. Evaluation of the formally exact expression, which depends upon the wall-ion direct correlation function, gives a precise measure of the amount of ion condensation in the planar double layer. Results are presented for 0.001, 0.01, and 0.1 M monovalent an...
متن کاملModeling the properties of lanthanoid single-ion magnets using an effective point-charge approach.
Herein, we present two geometrical models based on an effective point-charge approach to provide a full description of the lowest sublevels in lanthanoid single ion magnets (SIMs). The first one, named as the Radial Effective Charge (REC) model, evaluates the crystal field effect of spherical ligands, e.g. F(-), Cl(-) or Br(-), by placing the effective charge along the Ln-ligand axes. In this c...
متن کاملEstimation of profiles of the effective ion charge at ASDEX Upgrade with Integrated Data Analysis
The knowledge of the effective ion charge Zeff which indicates the degree of plasma pollution is of high interest, since the tolerable impurity concentration to achieve successful ignition of a fusion plasma is limited. The quantification of Zeff at ASDEX Upgrade has been carried out by means of Integrated Data Analysis in the framework of Bayesian Probability Theory which allows the combined a...
متن کاملEffective charge and free energy of DNA inside an ion channel.
Translocation of a single stranded DNA (ssDNA) through an alpha -hemolysin channel in a lipid membrane driven by applied transmembrane voltage V was extensively studied recently. While the bare charge of the ssDNA piece inside the channel is approximately 12 (in units of electron charge) measurements of different effective charges resulted in values between one and two. We explain these challen...
