Air ionisation variability in coastal and mountainous areas. Case studies from Romania [PDF]
Air ionisation is an important indicator of air quality, influenced by meteorological, geological, and topoclimatic factors, and may have implications for human health.

The enhancement of negative ion production in a volume Penning based source could be performed by the application of metal hydride cathode. Hydrogen isotopes are stored there in a chemically bound atomic state and desorbed from the metal hydride under ...

Effect of Negative Ion Generation on Complex Plasma Structure Properties
We propose a low-density discharge plasma model that takes into account the impact of oxygen admixture in typical conditions of complex (dusty) plasmas.

The paper describes a new phenomenon of the generation of the double electrical layer above the cathode spot surface. The neutralization of this layer leads to the reverse current of free electrons, generated due to negative ions ionization.

Fragmentation of metal(II) bis(acetylacetonate) complexes induced by slow electrons
Nowadays, organometallic complexes receive particular attention because of their use in the design of pure nanoscale metal structures. In the present work, we present results obtained from a series of studies on the degradation of metal(II) bis ...

Negative ion research at the Culham Centre for Fusion Energy (CCFE)
A summary of negative ion development work being presently undertaken at the Culham Centre for Fusion Energy is given. The small negative ion facility has an RF driven volume ion source with beam extraction at energies up to 30 keV. The extracted beam of

Resonance States of Negative Hydrogen-like Ions in Quantum Plasmas
We studied the 1Se and 1,3Po resonance states of negative hydrogen-like ions immersed in quantum plasmas. The exponential cosine screened Coulomb potential was considered to model the quantum plasma environment.

Negative ion sources for fusion are high densities plasma sources in large discharge volumes. There are many challenges in the modeling of these sources, due to numerical constraints associated with the high plasma density, to the coupling between plasma

Overview of the design of the ITER heating neutral beam injectors
The heating neutral beam injectors (HNBs) of ITER are designed to deliver 16.7 MW of 1 MeV D ^0 or 0.87 MeV H ^0 to the ITER plasma for up to 3600 s. They will be the most powerful neutral beam (NB) injectors ever, delivering higher energy NBs to the ...
