        "Description": "The Ion Mass Analyzer (IMA) of the ASPERA-4 package\nflown 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.\n\nReference: \nBarabash et al.,  The Analyser of Space Plasmas and Energetic Atoms (ASPERA-4) for the Venus Express mission,\nPlanetary and Space Science,\nVolume 55, Issue 12, 2007, Pages 1772-1792, ISSN 0032-0633,\nhttps://doi.org/10.1016/j.pss.2007.01.014.",
