In the work the design is described and results of experimental researches of plasma generator with the cold cathode for a source of negative ions are submitted. The generator consists of three consistently connected chambers with dosed gas leaking between them. The electrode system of the first chamber (of high pressure) and the second one (of low pressure), represents two-chambered inverse gas magnetron. The second chamber through an annular slot connects with the third (emission) chamber in
