Microwave resonator method for measuring transient mass gasification rate of condensed systems

Abstract The paper presents preliminary results on developing new contactless method for measuring transient mass gasification rate of condensed systems. The method is based on recording the forward power gain coefficient of microwave signal induced by the variation of tested material mass in the microwave gage of a resonator type. The gage design provides measurements of the gasification rate of a bored sample in conditions of intense gas blowing through. According to estimations the temporal resolution of the gage is not less than 1 ms and calculated spatial resolution comprises about few microns for the sample with outer diameter of 17 mm and bore diameter of 10 mm.
