Abstract: The general leakage detection techniques of space simulator based on a 3200m 2 chinese space simulator are presented. The intention of the paper is providing some helpful thoughts and means for leakage detection of a space simulator. The paper discusses in detail the helium mass spectrometer leakage detector and analyzes sensitivity of helium mass spectrometer leakage detector based on theory and practice. In the end the paper discusses how to design the whole leakage detection scheme of a large simulator.
