      <Description>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.</Description>
