A 2M~3 ISOTHERMAL CLOUD CHAMBER FOR THE STUDY OF ARTIFICIAL ICE NUCLEI

A 2m3 isothermal cloud chamber mainly for ice nucleation research is described in this paper.Its structure,attached instruments and experimental procedures are also presented.The experiments of determining the ice nuclei effectiveness for the Agl-containing aerosols produced by three formulations have been conducted and the results have been compared with those of the CSU 960-liter isothermal cloud chamber.All experimental results show that the chamber has advantages of stable performance and reproducibility.It would be expected to become a useful experimental facility for ice nucleation research.
