Claim:
1. A dual ion composition instrument for measuring plasma and ion populations comprising: a. a deflector/electrostatic analyzer subsystem and a time of flight versus energy subsystem wherein said deflector/electrostatic analyzer includes deflectors to bend a first collection of ions between greater than 1 eV/q to 100 keV/q into an electrostatic analyzer which focuses said ions onto carbon foil and wherein said carbon foil is positioned at an entrance of said time of flight versus energy subsystem and wherein said first collection of ions contact said carbon foil and generate secondary electrons and neutralized ions from said first collection of ions; b. entrance apertures in said deflector/electrostatic analyzer subsystem for introduction of a second collection of ions between 15 keV to 10 MeV/nucleon which contact said carbon foil and generate secondary electrons and ions from said second collection of ions; c. a start micro-channel plate in said deflector analyzer subsystem which detects said secondary electrons from said first and second collection of ions; d. one or more avalanche photo diodes in said time of flight versus energy subsystem which generates additional secondary electrons due to an impact of said neutralized ions from said first collection of ions; e. one or more solid state detectors in said time of flight versus energy subsystem which generate additional secondary electrons due to an impact of said ions from said second collection of ions; and f. a stop micro-channel plate in said time of flight versus energy subsystem, wherein said stop micro-channel plate detects additional secondary electrons due to impact of said ions from both of said first and second collection of ions.
