Research Interests:

Professor John Williams' research interests include modeling of erosion phenomena on ion thruster components such as ion extraction grids and hollow cathodes and experimental evaluation of plasma and ion beam interactions with materials for both aerospace and terrestrial applications. Professor Williams, a graduate of Colorado State University, worked at the Hughes Research Laboratory and the Electric Propulsion Laboratory before joining the mechanical engineering department in 2002.

Casey Farnell

Research Scientist II

Casey.Farnell@colostate.edu

Research Interests:

For his doctoral research, Dr. Farnell studied the measurement and formation of high energy ions formed near a hollow cathode. He is presently working to expand the depth of CSU's probe diagnostic abilities and knowledge.

Cody Farnell

Research Scientist II

Cody.Farnell@colostate.edu

Research Interests:

Dr. Farnell's doctoral research dealt with the simulation of ion thruster optics. Currently, he is applying simulation techniques to additional areas of research interest.

Seth Thompson

Research Interests:

Cost Effective Large Area Thin Film Coatings via Sputter Deposition

Paul J. Wilbur

Professor (retired)

pwilbur@engr.colostate.edu

Professor Paul J. Wilbur contributed 40 years of service to the Mechanical Engineering department at CSU. Reflecting his lifetime contributions to the electric propulsion community, he was awarded the "Medal of Outstanding Achievement in Electric Propulsion" in 2007. Professor Wilbur's research applied broad beam ion sources to applications such as spacecraft propulsion, surface modification of materials using ion beams, and plasma contacting to control the potentials of spacecraft. His most recent research focused on the development of emissive membranes, a promising new technology in electric propulsion.
