Abstract
To provide a plasma generator having plasma-generating zone of increased volume. A plasma generatorhas a cylindrical casingmade of a sintered ceramic produced from alumina (AlO) as a raw material. The casinghas a slit-like gas inletand a plurality of cylindrical gas outlets. From the gas inletto the top of the plasma-generating zone P, the slit width (the front-to-back direction with respect to the sheet of FIG..A, and the left-to right direction in FIG..B) is adjusted to 1 mm, and gas outletseach having an inner diameter of 1 to 2 mm are formed in straight line along the longitudinal direction of the plasma-generating zone P. The plasma-generating zone P has a square cross-section normal to the longitudinal direction having a side of 2 to 5 mm. Each of the surfaces of the electrodesfacing each other has a plurality of recesses (hollow portions). An elevated voltage of about 9 kV obtained from a commercial AC voltage (60 Hz, 100 V) was applied to the electrodes, to thereby supply a current of 20 mA. When argon gas was supplied through the gas inlet, even in the case where the electrodeswere separated at a spacing of 4 cm, stable linear electric discharge was observed.
