Title

Principles of Operation of Cloud Physics Instruments, II: Parallel Plate Thermal Diffusion Chambers

Abstract

Over the past 30 years the continuous flow thermal diffusion chamber (CFD) has evolved from a somewhat crude, static device to a rather well developed one that serves as the central measurement instrument in many cloud physics laboratories. The historical development of the thermal diffusion chamber will be outlined bringing us up to the present model in the UMR laboratory. The strengths and weaknesses of the chamber at each of its levels of development will be discussed.

Recent experiments with the UMR CFD will be discussed. These include coagulation rate measurements (carbon aerosol and polystyrene latex spheres), the properties of laser dye aerosols used as tracers, and the generation and characterization of carbon aerosols.
