Abstract

The straight and curved magnetic filter systems for plasma flow filtering from macroparticles are widely used. The considered magnetic filter systems are based on transport of a charged plasma components through the strait and curved channels that are optically opaque to neutral macrodrops and macroparticles. Description of computer code and results of the numerical investigations are presented. We have written a computer code based on the flux tube model or plasma-optical model. We have investigated dependencies of the ions transportation efficiency on magnetic field strength, magnetic field distribution, duct potential and sizes of the filter systems. The calculation results for the different design schemes of the filter systems are done.
