The concept of operation of a new microwave plasma source has been developed. Initial plasma is produced in the form of microwave micro-sparks excited on the metal-dielectric interface. Threshold of such a type of discharges, that have been observed and investigated in the General Physics Institute, is much smaller than for the microwave discharge freely localized in the gas medium. The basis for this source are also two resonance phenomena realization of which leads to the drastic decrease of plasma production threshold and to the generation of dense and hot plasma in a wide pressure range. One of these resonances can be classified as "geometrical" as it is determined by relation between plasma producing elements sizes and wavelength of microwave radiation. The second one - "plasma resonance" - is realized when cyclic microwave frequency coincides with the plasma Langmuir frequency. If density of this nonuniform plasma exceeds "critical" value conditions of nonlinear absorption of microwave energy in a "plasma resonance" region with transformation of it into electron component energy are coming into existence. Flux of energetic electrons and UV-radiation from place of local absorption of microwave energy leads to the formation of plasma "halo" in the volume much grater than the microwave energy release volume. Experimental setup in which "double resonance" conditions are manifested has been installed and put into operation. Microwave energy is transported to the cut dipole located on the quartz substrate. Microwave frequency = 2,45 GHz, pulse duration = 85-90 ms, pick power = 4 kW. Results of first experiments are presented.
