Two operational rf driving frequencies of 2 and 13. 56 MHz are employed in a 14-cm-diameter radio frequency (rf) plasma source under an expanding magnetic field. The changes in the radial profiles of the ion saturation current and the electron temperature are observed in the magnetically expanding plasma when changing the driving frequency. https://www.ealisboa.com/best-grab-Chocolate-Chip-Cookie-Purse-Spray-mega-super/
