Experimental Studies of Ion Emission from Rpi-ibis Facility and Modeling of Ion Motions
نویسندگان
چکیده
The paper presents the recent measurements of ion beams emitted from an RPI-IBIS plasma injector and some preliminary results of the theoretical modeling. The RPI-IBIS facility was equipped with coaxial electrodes made of thin molybdenum rods and a fast acting electromagnetic valve for the injection of a working gas. Plasma discharges were initiated with a variable time delay (τ ) after the gas injection and they were powered from a condenser bank charged to 30 kV, 30 kJ. The first part describes measurements of spatial distributions and energies of intense ion beams, which were performed by means of ion-pinhole cameras equipped with nuclear track detectors. Detailed analysis of ion massand energy-spectra was performed by means of a Thomson analyzer. The second part presents numerical simulations of ion motions in the RPI-IBIS facility, which were performed on the basis of a single-particle model. PACS: 52.50.Dg, 52.65.Cc, 52.65.Pp, 52.70.Nc.

Modeling of Chloride Ion Separation by Nanofiltration Using Machine Learning Techniques
In this work, several machine learning techniques are presented for nanofiltration modeling. According to the results, specific errors are defined. The rejection due to Nanofiltration increases with pressure but decreases with increasing the concentration of chloride ion. Methods of machine learning represent the rejection of nanofiltration as a function of concentration, pH, pressure and also ...

متن کاملModeling of esterification in a batch reactor coupled with pervaporation for production of ethyl acetate catalyzed by ion- exchange resins
In the chemical industry, process intensification is needed to meet important goals such as sustainable and eco-friendly processes. For esterification reaction the “produce more with less pollution” objective can be achieved by coupling reaction and separation in a so called integrated process. In this work a model for describing the esterification reaction of ethyl acetate in pervaporation mem...
