Plasma electron temperature measurement in a Mather-type plasma focus filled with hydrogen by a continuum intensity analysis

The electron temperature of the focus plasma in a Mather-type device energized by a 32 µF, 15 kV (3.6 kJ) single capacitor, with hydrogen as a filling gas is estimated. In this experiment, a multi-channel PIN diodes assembly is employed to record the X-rays from the focus plasma. The PIN diodes with some modifications are used as detectors in this experiment. 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 material. Using 3 µm, 6 µm, 9 µm and 18 µm 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.
