The IRM plasma instrument (G. Paschmann, PI) consists of two symmetrical quadrispherical electrostatic analyzers, one for ions and one for electrons, which measure the complete 3-D velocity distribution function in one spacecraft revolution (4s). The energy range covered is 15eV/q to 30 keV/q for electrons and 20 eV/q to 40 keV/q for ions. The angular resolution is 22.5°. Microcomputers within the experiment compute the moments of the distribution functions in real time. An additional retarding potential analyzer measured the flux of electrons between approximately 0 and 25 eV.
