 The ion mass spectrometer consists of two major                     
          subsystems.  One section, the High Energy Range                     
          Spectrometer (HERS) was designed to measure the ion                 
          abundances and the 3-dimensional velocity                           
          distribution outside the contact surface, where the                 
          ions are hot and there is considerable turbulence.                  
          The other section, the High Intensity Spectrometer                  
          (HIS) was designed to measure the abundances of the                 
          low-energy ions inside the contact surface, where                   
          the ions were expected to have higher abundances                    
          and lower temperatures.  This section contained                     
          separate Mass and Angle Analyzers.  Both sections                   
          of the instrument were powered and controlled from                  
          a common power supply and control unit.
