Quadrupole Trap

The Cloud Physics Lab is dedicated to studies of atmospheric clouds, including the physics of cloud particle formation and growth, homogeneous nucleation of ice, and particle-turbulence interactions. One of the major tools used in the lab is an electrodynamic levitation system (quadrupole trap) for suspending individual aerosol particles in the size range of roughly 10 to 100 micrometers diameter. Other facilities include sources of ultra pure water and dry (dewpoint less than -70 Celsius) compressed air, a large capacity refrigerated bath, and a chilled mirror hygrometer.
