description |
The results of the investigation of the radiation emission (X-ray and electron
emissions) from a 2.2 kJ plasma focus operated in argon are presented. Experiments
were carried out using the University of Malaya-Dense Plasma Focus (UM-DPF2)
device operated in argon. The charging voltage was 12 kV and the operating pressure
was in the range of 0.7–2.5 mbar. Several diagnostics techniques were employed during
the project, namely, high-voltage probe, five-channel PIN diode, Faraday cup, X-ray
spectrometer, and scintillator–photomultiplier as detectors. In addition, the Lee model
code was used to simulate the plasma focus discharge and the corresponding emission
in terms of X-ray yield and electron beam fluence were analysed and compared to the
measured results obtained. The main goal of our project is to conduct an in-depth
investigation on X-ray emission from the UM-DPF2 device within an optimum pressure
range, as well as the electron beam emission in the same pressure range. The X-ray
yield, electron temperature, and electron beam fluence of argon plasma at 1.5–2.0 mbar
were analysed. The charge and density of the electron beam is high at this pressure
range of argon gas. The model is used to compare the results of temporal evolution and
characteristics of X-ray yield and electron beam for 1.5–2.0 mbar pressure range of
argon gas in the plasma focus device. The pressure 1.7 mbar of argon was found to give
maximum X-ray yield and electron beam emission. A reliable low-energy plasma focus
device with X-ray emission or electron beam could be used as an electron beam source
in various technological fields. |
