Production of high-quality plasma discharges via real-time control of plasma current ramp-up using neutral gas injection in Aditya-U tokamak
Suman Dolui, Praveenlal Edappala, Kaushlender Singh +13
Robust control of plasma current ramp-up is an absolute necessity, as an efficient and uncontaminated plasma current ramp-up is essential for achieving prolonged, high-pressure tok…
Simulation study of neutral tungsten emissions for fusion applications
Ritu Dey, Ayushi Agrawal, Reetesh Kumar Gangwar +4
The article reports electron-impact excitation cross-sections and rate coefficients for neutral tungsten for three transitions (400.87 nm, 429.46 nm, and 430.21 nm) using the relat…
Stabilization of sawteeth instability by short gas pulse injection in ADITYA-U tokamak
Suman Dolui, Kaushlender Singh, Bharat Hegde +28
Experiments on ADITYA-U tokamak show a marked enhancement in the sawtooth period by application of short gas puffs of fuel that cause a modification of the radial density profile.…
Effect of convective transport in edge/SOL plasmas of ADITYA-U tokamak
Ritu Dey, Joydeep Ghosh, Tanmay M. Macwan +6
The 2-D edge plasma fluid transport code, UEDGE has been used to simulate the edge region of circular limiter plasmas of ADITYA-U for modelling the measured electron density profil…
