Electrons from secondary emitters are coupled into a discrete-dynode electron multiplier to provide spatial resolution in polar and azimuth angles. Electrons having 5<E(e)< 1500 eV are analyzed in 16 steps. A complete two-dimensional distribution is obtained in one spacecraft revolution and is read out every 24 s at 1024 bit/s.
