Are Gas Discharges Capable of Generating Maser Radiation?:—Part 2

Microwave radiation produced by the sliding (spark channel) discharges in the small gaps under the action of high (>MV/cm) electric field over the dielectric (plexiglass) substrates are studied in hydrogen/argon mixtures. Under certain condition, it is observed that the frequency of the radiation in the resonant cavity is 1.420 GHz. This frequency is related to the intrinsic property of the hydrogen atoms and corresponds to the radiation produced by the atomic hydrogen maser. Few examples how the resonant cavity affects the radiation produced by the quantum states of various bands is presented. This paper suggests why the super radiance is sometimes observed. Effect of the microwave radiation on the security of the electronic infrastructure is also mentioned.
