摘要
The dynamic behavior of a microhollow cathode sustained discharge with split third electrodes is experimentally investigated.The sustained discharge swells isotropically in the presence of a small amount of argon gas flow that is not clearly detectable with a conventional single third electrode.At high flow rates,the sustained discharge transitions to a fast-moving constricted discharge with an arc shape.The modified discharge structure causes a shift in current distribution over the third electrodes,and the current peak location varies linearly with the How rate over a certain flow range.Such linear behavior may be applied to in situ How velocity measurement.
