Progress report 1979 - 1980

Experimental and theoretical results are reported obtained by staff of the IPP-Prague in the years 1979-1980 concerning high-frequency heating of plasma in tokamaks, interaction of relativistic electron beams with a plasma, and applied plasma physics. Preliminary experiments on additional hf heating in a small TM-1-MH tokamak and the new data acquisition and processing system Andromeda are described in Chapter 2. In Chapter 3 the specifications of the high-power electron accelerator REBEX 2 and some of the applied diagnostic systems (X-ray detectors and equipment for the Thomson scattering of laser light) are described in detail. Work in applied plasma physics is concentrated to thin film formation and plasma chemistry (Chpt.4). In theoretical papers in the last chapter several interesting questions of high-frequency plasma heating and beam plasma interaction are discussed (e.g., particle transport in hf-heated plasma, reflexing electron beam phenomena, particle trapping).
