| Research Abstract |
To know how the respective ion species of thermal energy in the lower ionosphere obtain nonthermal energies is especially important for the understanding of the ion escape mechanisms in the polar ionosphere. We have developed a space-borne ion mass spectrometer for observations of the suprathermal ions related to the ion escape. In addition, we newly developed a low energy ion beam generator because ions of suprathermal energy are required for the laboratory calibration of the ion mass spectrometer.
