The Time-of-Flight Spectrometer SULEICA for Ions of the Energy Range 5-270 keV/Charge on AMPTE IRM

Abstract

The Suprathermal Energy Ionic Charge Analyzer (SULEICA) on AMPTE IRM is an instrument to determine the ionic charge state and mass composition of all major ions from H through Fe for energies of the suprathermal plasma (≈5 up to ≈270 keV/charge) by the use of electrostatic deflection, time-of-flight measurement, and energy analysis in solid-state detectors. With its acceptance fan of 400° X 10° the instrument scans a field of 360° by 40° in the satellite spin plane. The data contain counting rate information for the evaluation of absolute particle fluxes, live pulse-height events, and matrix rates for selected ions from on-board processing with a microprocessor.
