摘      要：The miniature design technology is an important trend in space *** spectrometer is used extensively in the space environment *** miniature ion mass spectrometer utilizes a 127° cylindrical electrostatic analyzer accompanied with a Time of Flight(TOF)unit based on ultrathin carbon foil to measure the energy spectra and composition of space *** Time of Flight technique has been used broadly in space plasma measurement.A new type of miniature method for the ion mass spectrometer is *** total mass of the instrument is1.8 kg and the total power consumption is 2.0 *** calibration results show that the energy measurement range is 8.71~43550eV,the energy resolution is 1.86%and the ion mass from 1 amu(1 amu= 1.67 × 10^(-27)kg) to 58 amu can be resolved by the miniature mass *** miniature ion mass spectrometer also has a potential to be increased in the field of view by an electrostatic deflecting system to extend its application in space plasma *** miniature ion mass spectrometer has been selected for pre-study of Chinese Strategic Priority Research Program on Space Science.
