Abstract
The authors discuss the expansion cloud chamber system known as the University of Missouri-Rolla-absolute Aitken nucleus counter. A review of the properties of an expansion chamber and how it creates a supersaturation are given and a critical examination is made of the assumptions in its operation, e.g. adiabaticity of the expansion. The design of the chamber is described in detail and an analysis of the propagation of errors is given for quantities measured and calculated. A short review of the performance of the chamber and some general comments relative to comparisons with other Aitken nucleus counting instruments are given. The chamber is capable of making measurements on aerosols of number concentration up to 106 nuclei/cm3 to an accuracy of about 10-15% at any desired supersaturation ratio up to the ion limit. Finally mention is made of other expansion chambers developed in this laboratory for measurements of homogeneous nucleation rates. © 1982.
