Relativistic calculations of electron impact excitation cross-sections of neutral tungsten
Ritu Dey, Ayushi Agarwal, Reetesh Kumar Gangwar +4
Reliable tungsten spectroscopy is essential for modelling and diagnosing tungsten-containing plasmas, particularly in edge/divertor conditions where neutral tungsten (WI) is produc…
Effect of static magnetic island on ITG of ADITYA-U tokamak
Vibhor Kumar Singh, Amal R Biju, Jaya Kumar Alageshan +10
Magnetic islands play a crucial role in regulating plasma confinement in tokamaks by interacting with micro-instabilities, such as the ion temperature gradient (ITG) mode. This wor…
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…
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…
