Solar wind contribution to the average population of energetic He+ and He++ ions in the Earth's magnetosphere

Measurements with the ion charge-energy-mass spectrometer CHEM on the AMPTE/CCE spacecraft were used to investigate the origin of energetic He<sup>+</sup> and He<sup>++</sup> ions observed in the equatorial plane at 3 ≤ <i>L&l...
