The Low Energy Electrostatic Analyzer for DSX
Abstract
The Low Energy Electrostatic Analyzer (LEESA) is an 90 degree quadraspherical ESA designed for the DSX satellite. LEESA measures electron and ion fluxes from 30eV to 50keV. LEESA has two input apertures with the same fields of view, one for ion and one for electron measurement. LEESA measures the directionality of the particles by offering 5 angular zones within a 110 degree FOV. LEESA is designed to operate at two different data rate levels. At the high data rate level the instrument will sample one step every 0.0125 sec, and at the low data rate the instrument will sample one step every 0.125 sec. Here we discuss the design characteristics, performance, and operation of the LEESA instrument.
