      <Description>The Energetic Particles and Ion Composition (EPIC) instrument (block diagram) is actually composed of two separate sensor and processing assemblies.
    * The STICS assembly (Supra-Thermal Ion Composition Spectrometer) uses a quadrispherical electrostatic analyzer followed by a foil/solid state detector time-of-flight (TOF) telecope to measure charge state, mass and energy of ions with energies of 30 - 230 keV/charge. It uses an electrostatic analyzer with a geometry factor of 0.05 cm**2 sr, time of flight and energy analysis.
    * The ICS assembly (Ion Composition Subsystem) measures mass and energy properties of energetic ions with energies of less than 50 keV to 3 MeV. It uses a pair of collimators with sweeping magnets to reject electrons, followed by TOF and energy analysis, with a geometry factor of 0.2 cm**2 sr. A thin foil/solid state detector electron telescope measures electrons higher than 30 keV. </Description>
