| Outline of Final Research Achievements |
A supra-thermal ion energy-mass spectrometer has been developed in order to measure ions with energies from 0.1eV to 100eV in a planetary magnetosphere in future. Shape and location of electrodes in an electrostatic energy analyzer were designed with numerical simulations. A time-of-flight (TOF) technique is used for mass analysis. As a result, a small instrument, but with high sensitivity has been obtained successfully. Testings with ion beam irradiations show that the sensor characteristics for energy, angular, and mass resolutions agree with the results of the numerical simulations. Also, a testing with ultraviolet photon irradiation show that the photon rejection capability of the sensor is enough.
