CONTROLLED THERMONUCLEAR RESEARCH QUARTERLY REPORT FOR DECEMBER 1958, JANUARY AND FEBRUARY 1959
A list of recent talks and publications by laboratory personnel is given. The efforts of the Pyrotron group were, for the most part, concentrated in two major areas. The first of these was directed toward the documentation and unprovement of the encouraging results obtained in the magnetic compression, adiabatic heating, and stable confinement of "low temperature" plasmas captured in experimental mirror machines. The other major area of effort was centered around the Felix experiment which is directed toward studying the problems of creating a hot plasma in a mirror machine by the injection and trapping of energetic particles. As part of a general program of plasma physics studies, effort has been going forward to exploit the steady-state plasma source known as P/sup 4/ in determining various fundamental effects, such as wave propagation and spectrum-line excitation, which can be studied effectively in a device such as thus. The Astron program is summarized and work on the E layer is discussed. The design of the first Astron model, including a 5-foot traveling-wave line for the electron injector, was completed and the components ordered. Major experimental objectives of the Livermore Pinch Program at present are to determine the nature of the small-scale turbulence that is interfering with the pinch and to investigate further the mechanism by which the plasma energy is carried to the wall. Two plausible suggestions regarding the nature of the turbulence were madei (a) that it is hydromagnetic and (b) that it is electrostatic in origin. In addition, several special lines of research, not directly related to pinch work, are being pursued. The Berkeley Pinch Program is concerned primarily- with the sheet pinch as exemplified by "Triax" and with rotating plasmas created in EXH "homopolar" geometries. A project was recently initiated with the objective of studying the excitation and propagation of plasma oscillations at microwave frequencies and developing plasma diagnostic techniques based upon the understanding of these plasmas. Theoretical research is briefly summarized. Design values, status of work, and development of components for the various programs are given. (W.D.M.)
