Notes:
Taking advantage of the iron core of the Saha Institute of Nuclear Physics (SINP) tokamak, a single turn primary coil was used to generate low power ohmically excited audio-frequency hydrogen plasma to clean the SINP tokamak vacuum vessel of adsorbed gases. This scheme allowed us to easily use available low voltage power transistors and other existing power supply components to generate audio-frequency voltage. Using this scheme the discharge cleaning system was tested successfully in a short period of 2–3 months. The system has been utilized to carry out initial discharge cleaning of the vessel as well as daily cleaning to achieve full designed parameters of our tokamak.
