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…
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…
Favorable modifications of Scrape-Off Layer (SOL) heat flux width through pulsed fuelling in ADITYA-U Tokamak
SK Injamul Hoque, Harshita Raj, Ritu Dey +19
Enhancement of the scrape-off layer (SOL) heat flux width has been observed in the ADITYA-U Tokamak following the injection of short fuel gas pulses. A notable reduction in paralle…
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…
