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…
Gyrokinetic simulation of the effect of transient fueling on plasma turbulence in ADITYA-U tokamak
Jaya Kumar Alageshan, Suman Dolui, Joydeep Ghosh +8
The gradient-driven microturbulence in ADITYA-U tokamak plasmas has been suppressed by injecting short gas puffs. The suppression of microturbulence increases the core temperature…
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…
Sensitivity of External Magnetic Field on the Change in Cross-section of a Toroidal Current
Suman Aich, Joydeep Ghosh, Rakesh L. Tanna +3
Due to any toroidal current column, the magnetic field is found to be sensitive as well as insensitive to its cross-sectional area depending on location of subject point, as predic…
PRISM: A MATLAB-Based Application for Structured Probe Data Management and Visualization in Tokamak Diagnostics
Priyanka Verma, Subhojit Bose, Harshita Raj +1
The successful operation of tokamak experiments requires accurate documentation, tracking, and visualization of diagnostic instruments, particularly electrical probes. Traditionall…
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…
