“…The waist diameter of the radiation beam ( ≈ 2 cm ) and the focus position ( focal lenght ≈ 37 cm ) of the antenna were experimentally obtained [ 5 ]. The electron density profile obtained from the ECE radiation were compared with the results obtained from a microwave interferometer installed in TCABR [ 6 ]. The electron density profiles can be approximated by parabolic equation in the form : A gas puffing injection system is normally used in the TCABR tokamak to control the electron density during the discharges.…”

“…Mais recentemente, um eletrodo de polarização foi instalado no TCABR para o estudo de regimes de alto confinamento ("modo H"), além de um sistema de Limitador Ergódico Magnético [68] (correspondente a este trabalho) e um sistema de injeção de pastilhas de impurezas (pellets) [67] , instalados para a investigação e controle de instabilidades de disruptura. Basicamente, a densidade de linha das partículas é dado pela seguinte expressão [72] :…”
