Further, by being able to precisely
measure electron density, it will now be possible to clarify through computer simulation the important behaviors of active ion species that play important roles in their interaction with living organisms and materials hazardous to the environment.
But in the case of atmospheric pressure low - density plasma, due to the influences of changes in the atmospheric pressure in a plasma as well as around the plasma, it was difficult to accurately
measure electron density.
By being able to
measure electron density with high accuracy in atmospheric pressure low - temperature plasma, it is no longer necessary to rely solely upon experience and trial and error.
Through this success, we demonstrated that we can
measure electron density with higher accuracy than previous interferometers and also comparatively easily.

density of
electrons in the tiny region of the sample directly below it.
In the large negative hydrogen ion source at NIFS, various types of diagnostics are available for
measuring negative hydrogen ion
density,
electron density, and other quantities.
Electron densities measured by radio - occultations (Pätzold et al. 2007) allow one to derive the overall structure of the ionosphere.

The instruments
measure atmospheric
densities and temperatures for both the electrically neutral (e.g., carbon dioxide, CO2, atomic oxygen, O, atomic hydrogen, H, and other species) and the electrically charged constituents (that is, ions such as CO2 + and O2 +, and
