Scientific paper

The manifestations of the induced surface currents as observed by the magnetic ion mass spectrometer (MIMS) and retarding potential analyzer (RPA) instruments on AE-C and AE-D are described. Data from these instruments are used to infer the source of some of the different secondary ions observed, as well as their time history and emission energy. It is noted that the emitted particles have a characteristic energy of approximately 1 eV in the spacecraft frame of reference and lack the normal ram energy possessed by the ambient ions. Alkali ions Na(+) and K(+), in addition to nonionospheric NO(+) and O2(+), are observed at low altitudes. With the exception of NO(+), all these are thought to be released by impacts of neutral N2 or O2 with the surfaces. These ion currents decrease with a time constant of about six weeks for the alkali and four weeks for the O2 ions.
