Abstract
A qualitative theory of gas breakdown had been developed for the conditions when the average energy of electron oscillations in an alternating field [MATH] exceeds the ionization potential of atoms I. The dependence of the growth rate of ionization [MATH] on ε0( ε0=102-104eV) is presented. Experimental investigations on the development of microwave breakdown in helium, argon and air have been conducted, in the region of E0/ω0 =1.5.10-8. 10-7V.s/cm (ε0=0.1-300eV) and pressures p=5.10-4-10-3torr. Satisfactory agreement between calculated and experimental dependences has been observed for ε0>>I.
