Robert W. Gruebel

Professor of Physics

Experience and Education

I served in the U.S. Navy as combat aircrew in the carrier USS Enterprise, CV 6, during WW II and flight engineer in transport aircraft until 1960. After 21 years I decided I didn't want to make a career of it so I entered college and received my B.S.(Highest Honors), M.S., and Ph.D in Physics from the University of Arkansas in 1968.

I joined the physics faculty at Stephen F. Austin State University in the fall of 1968. On leave of absence in 1982 and 1983, I served as Corporate Radiation Safety Officer for Halliburton Corporation, establishing the Radio-active Materials Management Program, the Nuclear Reactor decontamination program, and supervised the use of subsurface uses of RAM in oil field services, and returned to the university in 1983.

Research Interests

My dissertation research was in the field of structural studies of complex molecular liquids using X-Ray diffraction. Molecular and atomic distribution functions, as well as pair correlation functions, are determined by transforming the intensity data in momentum space to yield distribution functions in coordinate space. I established and built the theta-theta X-Ray diffractometer and equipped the Diffraction Laboratory to study liguids and metallic glasses.

I am a Master Tool and Diemaker and I set up, equipped and staffed the research machine shop in the Physics Department. I established the astronomy program at SFASU and designed and built the observatory to house the 18" telescope which I obtained from NASA and the 41" telescope for which I located the primary mirror and other optics. The 41" telescope was constructed in our Physics Shop by Norm Markworth, Bruce Rafert, and Bennet Montes( our Machinist)
