Dynamics of Ion Concentration in Air Affected by Applied DC Electric Field and Humidity
Paper in proceedings, 2018
Results of the measurements of air ion concentrations performed under different conditions including various sources of ions (natural factors and external corona discharge), applied DC electric fields and relative humidity of air are reported. It is shown that ion concentrations correlate with radon activity at zero field and a strong sweep out effect is observed due to the applied field. It is noticed that an increase of air humidity leads to a significant increase of the amount of negative ions in air. Possible reasons for the observed effects are discussed.
