FOCUS PLASMA ELECTR,ON TEMPERATURE MEASUR,EMENT BY CONTINUUM INTENSITY ANALYSIS

Abstract

The electron temperature of the focus plasma in a low energy Mather type device energized by 32J.i.F, 15 kV (3.6) kJ single capacitor, with Hydrogen as the filling gas is estimated. The ratio of integrated bremsstrahlung emission transmitted through foils, to the total incident flux as a function of foil thickness at various temperature is obtained for foil absorbers of designated material, Aluminium in our case. Using 3, 6, 9 and 18 iJ-m thick Aluminium absorbers, the transmitted X-ray flux is detected. By comparing the experimental and theoretical curves through a computer programme the plasma electron temperature is determined. Results show that the Hydrogen focus plasma electron temperature is about 580 eV.
