Ion-By-Ion Cooling Efficiencies
We present ion-by-ion cooling efficiencies for low-density gas. We use Cloudy (version 10.00) to estimate the cooling efficiencies for each ion of the first 30 elements (H–Zn) individually. We present results for gas temperatures between 104 and 108 K, assuming low densities and optically thin conditions. When nonequilibrium ionization plays a significant role the ionization states deviate from...
متن کاملPhotochemical degradation of azure-b with sulphate radical ion generated by peroxydisulphate ion with cupric ion
In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...
متن کاملObservations of fast anisotropic ion heating, ion cooling, and ion recycling in large-amplitude drift waves
Large-amplitude drift wave fluctuations are observed to cause severe ion temperature oscillations in plasmas of the Caltech Encore tokamak @J. M. McChesney, P. M. Bellan, and R. A. Stern, Phys. Fluids B 3, 3370 ~1991!#. Experimental investigations of the complete ion dynamical behavior in these waves are presented. The wave electric field excites stochastic ion orbits in the plane normal (') to...
متن کاملIon Beam Buffer Gas Cooling by a Rf-quadrupole
Beams with high brilliances are required for many applications e.g. for exotic and radioactive beam application. One way of reducing the necessary acceptance resp. increasing the transmission of accelerators is beam cooling by the statistical collisions with a buffer gas and a decreasing of the emittance in a short transport section in front of the accelerator. Our experimental setup is a combi...
