摘要：

A method of magnetic field measurement in plasmas, based on the coherent population trapping effect, was proposed and experimentally tested in a glow neon discharge. Both the strength and the orientation of the field can be determined with high resolution. A particular application to assessment of magnetohydrodynamic stability in electron-cyclotron resonance sources of multicharged ions is theoretically considered. Theoretical estimates show that parameters of plasmas in these sources satisfy the conditions at which the diagnostic works.
