요약2 In this study, the change in the characteristics of the saline solution discharge were investigated with the variation of driving condition. Regardless of the pulse polarity to the pin electrode, the amplitude of circuit current decreased but flew continuously with the insertion of series resistor to the power source when 5% duty ratio pulse was applied to a saline solution of 0.9% mass per unit volume in a pin to plate structure. The temperature of the discharge medium was measured from the spectrum of the hydroxy group molecular lines near 308 [nm] obtained during discharge, and the electron density using the Stark broadening of the Hβ line at 486 [nm], which is one of Balmer series hydrogen atomic line. The maximum temperature and electron density in the discharge medium decresed with the increase of series resistor inserted when the negative pulse was applied to the pin electrode. On the other hand, the positive pulse application to the pin electrode hardly led a temperature change while the change in the electron density was observed. It is estimated that the negative pulse application to a pin electrode and series resistor insertion in the driving circuit will helpful to widening the operation window in a liquid discharge.
