Several experiments, related to controlled thermonuclear fusion research and highly relevant for large size tokamaks, including ITER, have been carried out in ADITYA, an ohmically heated circular limiter tokamak. Repeatable plasma discharges of a maximum plasma current of~ 160 kA and discharge duration beyond~ 250 ms with a plasma current flattop duration of~ 140 ms have been obtained for the first time in ADITYA. The reproducibility of the discharge reproducibility has been improved considerably with lithium wall conditioning, and improved plasma discharges are obtained by precisely controlling the position of the plasma. In these discharges, chord-averaged electron density~ 3.0–4.0× 10 19 m− 3 using multiple hydrogen gas puffs, with a temperature of the order of~ 500–700 eV, have been achieved. Novel experiments related to disruption control are carried out and disruptions, induced by hydrogen …
