Microwave plasma was built to produce plasma in axial direction. Plasma was initiated in a Plaxy Glass made vacuum tube by 2.45GHz commercial magnetron and meanwhile system was driven by 14 Amperes DC current passing through 16cm inner diameter toroid. Measurements with a Longmuir probe and ICCD for optical spectrometry were used to characterize internal parameters like electron density, electr...
