        "Description": "The Ion Mass Analyzer (IMA) of the ASPERA-4 package\n flown on Venus Express provides ion measurements in the energy range \n0.01 - 36 keV/q for the main ion components H+, H2+, He+, O+, and for the \ngroup of molecular ions with M/q ration between 20 and 80 amu/e. IMA has a 90 deg x 360 deg field \nof view. Electrostatic sweeping performs elevation (+/- 45 deg) coverage. \nThe IMA sensor is a spherical electrostatic analyzer followed by a circular \nmagnetic separating section. A large diameter MCP with a discrete anode images \nthe matrix azimuth x mass.",
