Recent results of plasma research activities at the Instituto de Pesquisas Espaciais

Description

Recent results obtained in different experiments at the Institute for Space Research (INPE) are reported. An enrichment of 390% of carbon isotopes has been achieved in the plasma centrifege. The role of ion-acoustic turbulence in the formation of double layers has been experimentaly investigated. The turbulent spectrum has been measured and agrees quite well with the prediction of the modified Kadomtsev's renormalized theory. The characteristics of the gyrotron that is presently being built at INPE and new techniques for gyrotron design are discussed. Thecretical results on the generalized Spitzer-Harm problem, current drive in the start-up phase of Tokamaks, and quasilinear theory of beat-wave current drive are also presented. (author)

Abstract (Portuguese)

Apresentam-se os resultados recentes obtidos em diferentes experiencias no Instituto de Pesquisas Espaciais (INPE). Um enriquecimento de 390% de isotopos de carbono foi conseguido na centrifuga de plasma. Invenstigou-se o papel da turbulencia ion-acustica na formacao de camadas duplas. Mediu-se o espectro de turbulencia e considerou-se bom em relacao a previsao feita com a teoria renormalizada modificada de Kadomtsev's. Discutem-se caracteristicas do girotron que esta sendo construido no INPE e novas tecnicas para projetos de girotron. Apresentam-se tambem resultados teoricos do problema generalizado de Spitzer-Harm, direcao de corrente na fase inicial do Tokamak e a teoria quase linear da direcao de corrente. (autor)
