Escaping ion measurement with high time resolution on CHS

Review of Scientific Instruments, 2006
A scintillator-based lost ion probe can measure the temporal evolution of both the gyroradius and the pitch angle of energetic ions escaping a magnetically confined plasma. For the probe on the Compact Helical System, the time resolution of this detailed two-dimensional measurement is determined by a framing rate of the video camera that records the ...

A Mars magnetic field: Constraints from molecular ion escape

Journal of Geophysical Research: Planets, 1992
A model has been developed to investigate the transport of the upward flowing ionospheric ions from closed field lines of the Martian day and nightside “polar” magnetosphere into the solar wind interaction region. Guiding center ion trajectories in the polar regions, for a range of injection conditions of the convection electric field, gravitation, and

Escaping of planetary ions from Mars and Venus

Advances in Space Research, 2001
Abstract Escaping planetary ions and the resulted atmospheric and solar wind effects are discussed. Some observed global plasma and field regions near Mars and Venus are introduced, and similarities between the regions pointed out. The applicability of the global solar wind interaction models to interpret the observed ion-escape features is ...

Oxygen ions escaping from the dayside Martian upper atmosphere

Advances in Space Research, 2001
Abstract The dynamics of pick-up ions and the amount of their escape flux from the dayside Martian atmosphere are studied by using a test particle model. In the calculation, the O + ion production rate is used as a weighting value of the test particles.

Escape of ions from Earth under various magnetospheric conditions

Atmospheric loss processes together with sources and sinks at the surface govern the evolution of the atmospheric composition. At present-day Earth, the main dominant escape process is polar wind, which predominantly removes ionized oxygen atoms from the polar regions of the Earth.
