Xvi. Gaseous Electronics Academic and Research Staff A. Microwave Measurements of a Time-dependent Electron Velocity Distribution Function

A great deal of effort continues to be spent on the fundamental interaction of the particles of plasma physics. In this group we have concentrated on measuring diffusion coefficients, collision probabilities, particularly in partially ionized and fully ionized gases, and on the mechanism of production of radiation. Within the last few years we have studied the production of microwave radiation, and we are pushing this toward shorter and shorter wavelengths in the direction of the very long infrared. Our objective in this area is to study as many of the mechanisms involved in electron-atom and electron-molecule collisions as are susceptible to our microwave, infrared, and probe techniques. S. C.
