Data are presented showing that acceleration of electrons to energies in excess of 100-keV sometimes occurs on field lines associated with discrete auroral arcs. Velocity distributions suggest that acceleration is in directions primarily perpendicular to the magnetic field. The examples studied in the S3-3 data set indicate that the process can occur in the altitude range from the topside ionosphere to 5500 km. Our favored explanation is that the field-aligned beam excites upper hybrid waves when it interacts with the dense ionospheric plasma. The waves efficiently scatter the beam in both energy and pitch angle. ¿ The American Geophysical Union 1989
