Fine particle charges are determined under various circumstances such as plasma environment; photo-emission, electron, ion, and friction. It is very important to reveal charging mechanisms for investigating fine particle plasmas in the space and laboratory. The fine particles of several materials with various sizes were irradiated by UV light or electron beam in the laboratory. UV light or electron beam gun was set at another side of the chamber. The UV light source was 500 W halogen lamp, and the electron beam was generated by using TV electron gun. The acceleration voltage of the electron beam was varied from 50V to 500V. Test particles used were sphere glass, copper, aluminum, and volcanic ashes.
The charges and its polarity of the fine particles were observed by the Faraday cup at the bottom of chamber and measured by the oscilloscope. The observed pulse signals indicated the charge 1.3×103e~2.9×103e for glass particles, 1.3×103e~3.5×104e for copper particles and 1.7×103e~1.6×105e for aluminum particles by UV light irradiation. Also, the charge was ~2.2×103e for glass particles, ~3.8×103e for volcanic ashes ~6.8×103e for aluminum and ~4.7×103e for copper particles by electron beam irradiation. We could reveal that the relation between the fine particle charges and particle size or the electron beam energy from experiment.
