Possibilities and analytical properties of the radiofrequency plasma pencil operating in the continuous and in the pulsed mode

Popis výsledku v původním jazyce

A two-electrode capacitively coupled plasma jet discharge operating at a 13.56 MHz symmetrical sinusoidal frequency carrier wave in a continuous mode and in a pulsed mode is described in this paper. The Internally pulsed mode was realised by the frequency modulation using a symmetrical rectangular frequency of 22 kHz with a duty cycle of 90%. The pulsed mode has an effect on the electron number densities ranging from 1 x 10(14) to 1.2 x 10(15) in the pulsed mode and from 1.7 x 10(14) to 1.0 x 10(15) cm(-3) in the continuous mode, gas temperatures 670-950 K in the pulsed and 630-880 K in the continuous mode, excitation temperatures 3100-4250 K in the pulsed and 3500-4280 K in the continuous mode, slopes and intercepts of the calibration lines and limitsof detection and a weak effect on the coefficients of determination. All these parameters were measured at three different positions from the sample inlet of the plasma pencil.
