Mission Name: STP P78-2This experiment (SC10) measured the absolute potential between the satellite and the plasma using a 101.7-m tip-to-tip dipole antenna. The antenna elements were copper-beryllium stem extendable antennas and were 0.64-cm diameter tubes when extended. Two 50-m elements plus the 1.7-m spacecraft body made the total length 101.7 m. The antenna elements were insulated except for 20 m at the ends. Thus, for ambient plasma conditions, the conducting segments of the antenna were positioned outside the sheath region. The experiment measured dc electric fields from 0.1 to 20 mV/m and ac fields in the frequency range from 3 to 200 Hz from 1 to 100 microvolts/m.
