Influence of insulator length on the electron temperature in the coaxial electrode of Plasma focus device

Summary form only given. We have generated the argon plasma in the diode chamber based on the established coaxial electrode type and investigated the emitted visible light for emission spectroscopy. We applied various voltages 2-3.5 kV to the device by 0.5 kV. and obtained the emission spectrum data...

Description
Summary:Summary form only given. We have generated the argon plasma in the diode chamber based on the established coaxial electrode type and investigated the emitted visible light for emission spectroscopy. We applied various voltages 2-3.5 kV to the device by 0.5 kV. and obtained the emission spectrum data for the focused plasma in the diode chamber on the diverse argon pressure. The Ar I and Ar Il emission line are observed. The electron temperature and ion density have been measured by the Boltzmann plot and Stark broadening from assumption of local thermodynamic equilibrium (LTE). We changed the length of insulator which is covered with the anode and cathode and measured the electron temperature on the its diverse insulator type. It can be shown that the electron temperature will be influenced by the insulator length in argon plasma with coaxial electrode.
