          The purpose of this work was the research of some constructive schemes of ion source intended for electromagnetic isotopes separasion.It is necesarry to note the isotopes separation of the several high -melting elements (f. e. platinum-palladium group) presents serious problem. This article is also devoted to this scientific theme. the review of works' results with various construction of the ion source, which is located inside a magnetic field and outside, is here contained.Total currents of platinum isotopes are obtained up to 5 mA. In this article new construction of the ion source on the basis of cathode sputtering (ion source "with the isolated electrode") is offered and investigated. Such ion source construction using the effective cathodes and special isolated electrodes allows reaching the interesting "selfsputtering" mode. To increase of an overall yield of a ions source the analysis had been held.
