Processes of energy cascade from suprathermal to thermal electrons significantly affect the thermal structure of the lower ionosphere. The Suprathermal Plasma Analyzer (SPA) was developed to measure an energy distribution of thermal and suprathermal electrons (< 5 eV). The principle of this analyzer is based on the innovative combination of a second harmonic method and a channel electron multiplier. Outstanding point of this analyzer are: 1) accurate calibration of electron energy within the order of 0.01 eV, and 2) the energy resolution smaller than 0.15 eV. The SPA was installed in the sounding rocket S-310-37 and observed the electron energy distribution function at the height from 100 km to 140 km.
