Mission Name: Explorer 14This experiment was designed to detect and study the positive ion component of the solar plasma. The instrument consisted of a quadrispherical electrostatic analyzer. During each energy scan, the voltage applied across the analyzer plates logarithmically decreased so that the instrument continuously covered the energy range from 18,000 down to 200 eV-per-unit-charge. This took 170 s. The instrument had a fan-shaped angular acceptance for positive ions of 10 deg by 80 deg (full width at half maximum). The instrument was located on the lower hemisphere of the spacecraft with the 80-deg view angle contained in a spacecraft meridian plane. The only useful data were obtained during the October 7, 1962, geomagnetic disturbance. A few more details regarding experiment design are given in Wolfe, J. H., and R. W. Silva, J. Geophys. Res., v. 70, pp. 3575-3579, August 1965. NSSDC has no data from this investigation.
