Based on the previously proposed new type of charged particle analyzer CAMERA [Vaisberg et al., 2001; Vaisberg, 2003; Vaisberg et al, 2005] we developed energy-mass spectrometer of ions, which provides 2π-FOV image of ion flux. We describe electro-optical scheme of instrument and the results of its numerical and laboratory tests. Such an instrument can find application in magnetospheric studies and in the investigations of various objects in the solar system.
We also use this design for Secondary Ion Mass Spectrometry (SIMS) of solar system bodies by analysis of secondary ions sputtered from the surface by the solar wind flow. Our first experiments in this direction will be performed on two lunar landers (Luna-Glob and Luna-Resource) and one lunar orbiter (Luna-Glob). We also will make an attempt to use our ion energy-mass spectrometer for measurements of secondary ions neutrals sputtered by the solar wind from lunar regolith.
The goals of Resonance project include investigation of wave-particle interactions and processes in magnetospheric flux tubes’ filling with plasma during natural and actively induced processes in magnetosphere and ionosphere. We review two instruments included in scientific package of Resonance project: 2-D ion energy-mass-spectrometer and 2-D electron energy spectrometer. These instruments are based on electron-optics scheme that provides simultaneous measurements of velocity distribution within energy range E0÷10×E0. This decadal energy range can be selected within energy range of 10 eV to 30 keV (as determinate by HV supply).
