Abstract:A pulsed oscillating power amplier has been developed to apply high frequency biasing voltage to an electrode at the edge of STOR-M tokamak plasma. The power amplier can deliver a peak-to-peak oscillating voltage up to 120V and current 30A within the frequency range 1kHz-50kHz. The electrode is located in the equatorial plane at radius ρ = 0.88. The frequency of the applied voltage has been varied between discharges. It is observed that the plasma density and soft x-ray intensity from the plasma core region us… Show more
