Sensor Assembly
The sensor assembly consists of the heated saturator, liquid wick,
cooled condenser, and optics. In this assembly, sample particles
serve as condensation nuclei and are grown in a supersaturated
atmosphere of butanol. The large droplets are easily detected using
a conventional focused laser and solid-state detector.
