• Scott Robertson

  

  Scott Robertson is an experimental plasma physicist and a professor in the physics department at the University of Colorado. Scott's research is in “dusty plasmas” in the laboratory, the ionosphere, and in space. His laboratory experiments have been directed at understanding the physics of dust on the lunar surface, including photoelectric, triboelectric, and plasma charging of dust that is either suspended electrostatically or resting on surfaces.

  
  

  Results of these experiments include measurements of the charge on individual dust particles and images of simulated lunar dust levitated above, and moving on, surfaces. In the ionosphere, the dust is meteoritic smoke particles that can be the nucleation sites for noctilucent clouds that form in the polar summer. Scott has also developed charged dust detectors and mass analyzers that have flown on numerous rockets to find the charge residing on these particles.
