First Plasma Commissioning and Operational Highlights from India's First Spherical Tokamak at IPR
Kishore Mishra, Aditya Verma, N. Mansoori +72
A compact Spherical Tokamak(ST) is commissioned at Institute for Plasma Research (IPR) to explore low aspect ratio tokamak physics and technologies that complement to the existing…
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…
