title: Soft x-ray emission from millimeter-wave electron cyclotron resonance discharge.
abstract: This work is devoted to the experimental investigation of incoherent soft x-ray radiation from an electron cyclotron resonance discharge with pumping by a millimeter-wave beam from a gyrotron. The basic contribution to the x-ray spectrum was shown to be produced by a plasma emission in the wavelength region 4.5-12 nm. The power of the x-ray emission from the ECR discharge was about 35 kW, and the efficiency of conversion of the gyrotron radiation into an x-ray emission exceeded 25%.
