Academic Research

The formation and composition of clouds are a high priority for an improved understanding of atmospheric processes. In our experiments, we generate condensation nuclei (clusters) of atmospherically relevant atoms or molecules by the supersonic expansion of a gas into an ultrahigh vacuum. 
By varying the experimental parameters, we can change the particle size over many orders of magnitude, from 1 to approximately 1 million molecules per particle, corresponding to nanoparticles up to 20 nm in diameter. In this project, we characterize the particle size using Rayleigh scattering. 
The task will be to measure particle size as a function of experimental conditions to improve understanding of the condensation process.
