摘要

To meet the needs of the development of aerospace industry, it is necessary and inevitable to develop a quick-response, high-accuracy and continuous monitoring sensor to test hydrazine. The quality of ionization chamber of the detector determines directly the test sensitivity of weak signal. This paper focuses on the influence of electrode spacing on the sensor sensitivity. Based on the Freedman's theory, an experiment was conducted to find out the optimal spacing between two electrodes, so as to reach the maximum efficiency of the ionization chamber.
