Efficient laser-plasma line X-ray source was developed. X-ray generation was optimized by the laser pulse duration alteration and using the local helium blowing into the microplasma region on a copper target located in atmospheric conditions. Measured Кα x-ray flux of 2 •10^7 ph/pulse/2π sr and conversion efficiency of 10^-5 were achieved correspondingly.
