Abstract:

This report details the development at the Space Sciences Laboratory of the University of California, Berkeley of the SupraThermal Electrons, Ions, and Neutrals AF-STEIN instrument for the Air Force that can measure essentially all important suprathermal approximately 4 to 200 keV particle populations associated with solar disturbances, magnetic storms and magnetospheric substorms. AF-STEIN has several distinct advantages over standard detectors flown on low-earth-orbit LEO satellites. AF-STEIN provides the sensitivity, temporal resolution, energy resolution approximately 1 keV FWHM, dynamic range, and energy range to simplify and improve measurements of suprathermal particle populations in LEO. Typical charged particle Silicon detectors have energy thresholds of approximately 20keV as opposed to the 2-4 keV threshold developed here. Unlike an electrostatic analyzer which measures one energy band and species at a time, AF-STEIN observes all energies simultaneously and with far higher sensitivity as well as charge state sorting up to several tens of keV.
