The theoretical treatment of the time dependent ambipolar diffusion of a plasma has been extended through the removal of one of the limitations imposed in earlier consideration. The assumption that the flow-velocity of the ionized particles is small compared to their thermal velocity is analyzed, and a method for eliminating this assumption is suggested. Further studies of the electron densities, produced when the gas is heavily preionized before the application of the theta pinch, were made using a laser interferometer. Electron densities observed in these studies were found to be little different than those measured with only weak preionization. Many of the technological problems associated with the scattering of laser light from the high density plasma are being resolved. A high energy Q-switched laser is being assembled and tested. Author
