2.2.6 spase://CDPP/Instrument/AMDA/VEX/IMA IMA Ion Mass Analyzer 2016-07-10T00:00:00Z The Ion Mass Analyzer (IMA) of the ASPERA-4 package flown on Venus Express provides ion measurements in the energy range 0.01 - 36 keV/q for the main ion components H+, H2+, He+, O+, and for the group of molecular ions with M/q ration between 20 and 80 amu/e. IMA has a 90 deg x 360 deg field of view. Electrostatic sweeping performs elevation (+/- 45 deg) coverage. The IMA sensor is a spherical electrostatic analyzer followed by a circular magnetic separating section. A large diameter MCP with a discrete anode images the matrix azimuth x mass.
